The application of the instruments of architectural planning and structural design for the compensation of road traffic noise to permissible levels in the urban development area
type: item
description: The purpose of our research is aimed to fulfill the third provision of "Sustainable Development" – "Sound Health", which organically transitions to the implementation of the eleventh provision – "Sustainable Development of Cities and Communities". In general, the provision of "Sustainable Development" is the basis that allows modern cities to reach the level of Smart City. The methodology of research relies on the concept that forms the basis of the compensation technique aimed at reducing the harmful acoustic impact on people located in the adjacent territorySpecial pavilion-type "shelters" are placed on the noise-affected territory, in the middle of which the recreational function can be performed in conditions of significantly reduced harmful acoustic impact on people from external sources by architectural planning and structural design means. The findings of the study indicate that the acoustic calculation of the necessary noise protection of the external structures of the designed "shelters" of various volume-planning and structural solutions, located on the adjacent territory near the complex of residential buildings No.5 - No.12 with preschool educational institutions and a school (Fig. 6). Forecast of the expected isolation of airborne noise of "shelters" external enclosure was prepared, an assessment of the noise regime of "shelters" premises was carried out in comparison with the permissible noise norm. The originality of this research lies in the predictionof the noise regime inside the "shelters", performed within the framework of the energy and wave theory of applied acoustics. Calculation of the compensating action of the "shelters" takes into account the combined action of air noise by the structures of the external enclosure and the reduction of noise by the input units in the "shelters", presented in plain view by chamber mufflers. Special pavilion-type "shelters" allow protecting people who are in recreation areas in the territories adjacent to res…

title: Analysis of the effectiveness of reinforcing bent reinforced concrete elements by extending the compressed zone: review of experience and prospects for application to beams with basalt-plastic reinforcement
description: The global problem of reinforced concrete structure degradation caused by steel reinforcement corrosion has accelerated the transition of the construction industry toward non-metallic composite reinforcement, particularly basalt fiber-reinforced polymer (BFRP) bars. BFRP reinforcement offers significant advantages, including high tensile strength, complete corrosion resistance, and environmental sustainability. However, the absence of a yielding plateau and the relatively low modulus of elasticity of BFRP reinforcement require specific design approaches. To prevent sudden rupture and brittle structural failure, international standards recommend designing such beams as over-reinforced members, which ensures a safer failure mode through concrete crushing in the compression zone but results in increased serviceability deflections and limited utilization of the tensile strength potential of composite reinforcement. This study aims to summarize international experience in strengthening flexural reinforced concrete elements by increasing cross-sectional dimensions and to theoretically substantiate the feasibility of applying concrete overlays to BFRP-reinforced structures. A systematic analysis of previous studies demonstrated that increasing the compressed zone height improves structural stiffness, shifts the neutral axis upward, and increases load-bearing capacity by approximately 60–88%, while showing considerable potential for improving the performance of BFRP-reinforced beams.

Effectiveness of using fiber-reinforced concrete in columns with external corner reinfocement
type: item
description: This article examines the effectiveness of using concrete reinforced with basalt and steel fibers in columns with external corner reinforcement. Concrete columns with external corner reinforcement are quite reliable in service, as they can withstand significant loads for extended periods under ultimate conditions. This is made possible by the fact that the concrete in a column with external corner reinforcement operates under a volumetric stress state, as the stirrups prevent its free movement (stirrup effect). At the same time, concrete operating under a complex stress state increases its strength and prevents the stirrups from losing stability. To this end, in the first stage, a calculation was performed for a column made of ordinary concrete with a cross-section of 25 × 25 cm, a length of 4.8 m, and 50 × 50 × 5 mm angles, fastened with 8 mm diameter clamps spaced 200 mm apart, using C20/25 concrete. In the next stage of the study, cross-sections were selected using concrete with steel and basalt fibers at various thicknesses of the metal angles. To calculate fiber-reinforced concrete columns, we use the methodology proposed in [1], in which, instead of the prismatic strength of concrete, we will consider the reduced prismatic strength of fiber-reinforced concrete. Based on the calculations performed, it can be concluded that adding steel or basalt fibers to the concrete of a column significantly affects its dimensions, weight, and cost

Simulation Models of the Lower Tailwater Structure of Road Culverts
type: item
description: The problem of excess kinetic energy dissipation in the lower tailwater of road culverts [15] and drainage structures is considered. The paper presents an analysis of the operating conditions of active-type energy dissipators based on a pressureless energy-dissipating diffuser concept. Three fundamental types of dissipator action on the flow — reactive, dissipative, and distributive — are reviewed as the theoretical framework [1–3]. The factors determining the effectiveness of a spatial energy-dissipating diffuser are identified: the flow rate parameter, the relative width of the discharge channel, the throat opening, the wall installation angle, and the wall height. A D-optimal experimental design was implemented to obtain statistical models of the diffuser operation. Comparative hydraulic model tests of the conventional retaining-wall dissipator and the energy-dissipating diffuser were conducted under varying flow discharges and tailwater submergence conditions. Results show that the relative near-bed velocity downstream of the diffuser is approximately three times lower than that downstream of the conventional retaining-wall dissipator.

Investigation of construction mixture preparation processes in a universal mixer
type: item
description: Modern construction conditions are characterized by increased requirements for efficiency of preparation and transport processes for construction mixtures with varying consistency within mobile technological systems. The study aims to analyze dry, semi dry, and plastic construction mixture mixing features and to justify rational mixing and conveying equipment design schemes ensuring coordinated preparation and material delivery process progression. The study considers structural mechanical characteristics of construction mixtures with different consistency and their influence on mixing conditions within the mixer working volume. Comparative analysis covers gravity and forced action mixers considering medium particle motion character and homogeneous mixture composition formation intensity. Main methods for construction mixture transport to application point are analyzed and efficiency of screw conveying units within mixing feeding installations is determined. The obtained results can be used for selection of equipment design and operating parameters for preparation and delivery of construction mixtures with varying consistency under construction site conditions.

Modern development trends in plastering units, stations, technological sets, and their control coordination systems
type: item
description: Modern construction industry development is characterized by increased finishing operation productivity, quality, and resource efficiency requirements, with a significant share attributable to building mortar preparation, transportation, and application processes. Within total construction and installation work labour intensity structure, plastering operation share remains among the largest, necessitating further plastering process mechanization and automation. Plastering unit and station operation efficiency is largely determined by mixing and pumping unit design parameters, different mobility mortar supply stability, pipeline system pressure pulsation levels, and equipment operation mode coordination with building mixture rheological characteristics. Extensive morally and physically obsolete equipment use leads to technological process productivity reduction, energy consumption increase, and material application quality deterioration. At the same time, modern construction equipment development trends are associated with energy saving drive implementation, automated control system integration, process parameter digital monitoring technology application, robotic mortar application complex deployment, and mortar pump and mixing device design improvement. This necessitates existing plastering unit and station design feature system analysis and promising further development direction identification.

Theoretical substantiation of the parameters of the concrete batching plant feeding system for stabilising the mass flow rate of moist materials
type: item
description: The article presents a theoretical substantiation of the parameters of the feeding system of a concrete batching plant for stabilising the mass flow rate of moist fine aggregate with a particle size of 0–5 mm. It has been established that, at a sand moisture content of W ≥ 4–6%, the standard hopper geometry with a wall inclination angle of α = 60° does not ensure mass flow according to the Jenike criterion, resulting in the formation of dynamic arches and a pulsating material discharge with a coefficient of variation of CV = 15–25%. A scientific hypothesis is proposed that the flow regime can be converted from funnel flow to mass flow by artificially reducing the effective internal friction angle below its critical value through the mechanical disruption of capillary bonds using an active loosening device with a horizontal shaft and pins arranged at 90° angular intervals. Based on the theory of limit equilibrium and the Janssen equation incorporating cohesion, an analytical model describing the formation of dynamic arches was developed, and a design equation for the critical angular velocity (ωcr) was derived. An integrated mathematical model of the material mass flow rate was also established. It was found that, at an operating angular velocity of ωop ≥ 2.5ωcr, the coefficient of variation of the mass flow rate reaches CVQ ≤ 3% for W ≤ 6%, satisfying the requirements of DSTU B V.2.7-96:2000.

Machine Diagnostics in Mechatronic Systems: Analysis Methods and Intelligent Technologies
type: item
description: The article examines modern approaches to machine diagnostics within mechatronic systems using signal processing methods and intelligent machine learning technologies. The structure of mechatronic complexes is analyzed, and their specific features that influence the development of diagnostic models are identified, including the high level of interdependence between mechanical, electronic, and software components. The feasibility of applying hybrid diagnostic systems is substantiated, where convolutional neural networks (CNN) are employed for automatic extraction of informative features from vibration and sensor data, while recurrent networks such as LSTM provide analysis of the temporal dynamics of processes and prediction of degradation states. A generalized theoretical diagnostic model is proposed, combining spectral methods of preliminary signal processing, multisensor data integration, and modules for technical condition prediction. The obtained results demonstrate the high effectiveness of intelligent algorithms in detecting early signs of faults, even under noise disturbances and varying operating modes. The proposed approach can be applied in maintenance systems at industrial enterprises to enhance the reliability and extend the service life of mechatronic systems.

Flexural Behaviour of 3DCP Beams with Expanded Metal Sheet Reinforcement: Experimental Investigation and Numerical Verification
type: item
description: An experimental and numerical study of the flexural behavior of 3D-printed concrete (3DCP) beams reinforced with expanded metal sheet are presented in this paper. Four-point bending tests on beams of 3DCP were carried out in accordance with DSTU B V.2.7-214:2009, recording load–deflection curves and strains. The 3DCP showed an equivalent axial tensile strength 30–45 % lower than that of class C16/20 concrete. Correctly oriented sheet reinforcement increased failure load and flexural toughness by about 30–40 %, while a 3D FE model in LIRA-FEM reproduced ultimate loads within 5–10 % but underestimated stiffness.

Conditioning of boron-containing LRW with composite binders
type: item
description: Modern management of liquid radioactive waste (LRW) requires mandatory conditioning, which they practically carried out by cementing, most often with Portland cement. As an alternative to cementing, alkaline binders are used, which are chemically more stable, increase strength over time, and do not pollute the atmosphere with CO2. Most often, the basis of such binders is granulated blast furnace slag in combination with alkaline substances. As a development of LRW management, the direction of conditioning with composite binders we formed, which combines Portland cement and blast furnace slag in composition. Composite binders can take into account the positive properties inherent in the constituent components, while the properties will depend both on the physicochemical parameters and on the conditions under which the LRW is conditioned. The work shows that boron-containing LRWs with a pH > 12 and a total salt content of 60.2% can be conditioned with composite binders, with a ratio of granulated blast-furnace ground slag (particle size < 80 μm): PC-500 cement as 1:1 with a compressive strength > 3 MPa at a temperature of 55 - 60C. The amount of LRW (imitate) in the compound can be 35 - 40%. Alkaline substances included in the LRW composition they used as a binder hardening activator, without the addition of additional alkalis and liquid glass. Depending on the types of components involved: Portland cement, blast-furnace slag or composite binder, samples of compounds with a compressive strength of mainly > 10.3 MPa we obtained.

Results of the Study of Mining and Processing Plant Waste for the Construction of Motor Roads and Railway Tracks
type: item
description: The pavement of technological motor roads consists of rock formations extracted from the quarry. With the current increase in the tonnage of quarry transport, the road pavement structure is also changing. On the other hand, the construction of the railway subgrade on dumps and stripping horizons of the quarry leads to increased operating costs for track repair and maintenance works. The relevant task is to investigate the physical and mechanical properties of rock materials from PJSC “Inhulets Mining and Processing Plant” (InGZK), to develop optimization measures and recommendations for the efficient use of these rocks for technological road pavements and the construction of railway embankments within the quarry and waste dumps of PJSC “InGZK”. The aim of this paper is to study the physical and mechanical properties of the rock formations of PJSC “InGZK” and to determine the grain-size composition of crushed stone produced from dense hard rocks. To determine the physical and mechanical properties of the rock materials of PJSC “InGZK,” the following were sampled: iron ore rock (migmatite) and associated dense rock types such as amphibolites, schists, granites, substandard quartzites, oxidized quartzites, oxidized jaspilites, and arkosic metasandstones. Experimental studies provided the physical and mechanical parameters and data on the grain-size composition of crushed stone from these rocks. Examination of the structure of amphibolites and schists from PJSC “InGZK” showed that these rocks have a dense texture, which provides high strength (1000 and 1200), and their mineral inclusions do not require additional beneficiation. The grains of crushed stone obtained from amphibolites and schists of PJSC “InGZK” have a cubical shape and high void content. This opens up the possibility of their use in the construction of roads and railway tracks, as well as in concrete and reinforced-concrete structures.

Experimental studies of the strength of masonry under axial and local compression
type: item
description: Masonry is one of the traditional building materials that remains highly relevant in modern civil and industrial construction. Determining its strength characteristics, especially under compressive loads, remains an important scientific and technical task, since such forces prevail in load-bearing walls, columns, and other structural elements of masonry. The compressive strength of masonry is affected by numerous factors, including the strength and geometric properties of the units, their shape accuracy, the presence of voids, the mortar strength, the deformation characteristics of hardened mortar, the workability of the mortar mix, the bond strength between mortar and masonry units, the degree of joint filling, the bonding pattern, and the overall quality of workmanship. When determining the strength of masonry under local compression, the nature of the sample's destruction is taken into account, on the basis of which a corresponding kinematic scheme is developed that determines the main parameters that affect the strength of the masonry. One of the key issues is the lack of a unified approach to determining the geometric parameters of the samples used for testing. The objective of this study is: 1. to develop scientifically based recommendations for the optimal shape and size of standard samples that allow the most reliable assessment of the axial compressive strength of masonry based on test results; 2. to consider the case of local compression of walls by stamps located near the end face with a width less than the wall thickness.

Urban Regeneration and Post-War Recovery: Prospects for Sustainable Development in Ukraine
type: item
description: This article examines the integration of urban regeneration strategies with the challenges of post-war reconstruction in Ukraine. Drawing on European experience, specifically the Leipzig Charter and related approaches, the paper highlights that effective recovery of war-damaged territories requires not only physical rebuilding of infrastructure but also comprehensive economic, social, and cultural revitalization. The analysis emphasizes the limitations of traditional “restore as before” models and argues for modern concepts such as compact cities, mixed-use development, and sustainable technologies. Special attention is paid to demographic shifts caused by the war, including depopulation, aging of the population, and the rise in the number of people with disabilities, which demand inclusive and adaptive planning. The essay also considers the potential of small and medium-sized towns, which may become new growth centers through the integration of internally displaced persons. Case studies from both European and Ukrainian contexts demonstrate that integrated strategies, that is combining participatory planning, decentralization of housing, and economic diversification, represent the most effective model for Ukraine’s long-term urban renewal.

type: item
description: The article analyzes the research of scientists who studied the work of retaining walls under different soil conditions, and their contact interaction with the base. Examples of recent designs of retaining walls and their use are given. It is stated that the goal is to study the stress-strain state of a retaining wall with a structural surface, considering its contact interaction with the ground mass. The main stages and features of mathematical modeling of the retaining walls and soil foundation interaction in the conditions of a flat problem with the help of LIRA 9.6 software have been described. As a result, the nature of the retaining wall work has been analyzed under various conditions of interaction with the base and with different parameters of the retaining wall rigidity. The relationship between the retaining wall rigidity and the resulting equivalent stresses in the soil foundation under various conditions of interaction has been established. It has been concluded that on the contact surface of the retaining wall with a structural surface, the effect of stresses redistribution is achieved and the carrying capacity of the foundation soil is increased due to the formation of elastic cores and unloading arches.

Contact interaction between foundation structures and subsoil and its effect on the stiffness characteristics of structural frames in high-rise buildings
type: item
description: The increasing proportion of high-rise buildings in dense urban development requires a reliable assessment of contact interaction between foundation structures and subsoil. For such buildings, serviceability and structural reliability are governed not only by absolute settlements, but also by differential settlements, angular distortion and their effect on the spatial behaviour of the structural frame. The aim of this study is to develop a consistent engineering procedure for assessing the subsoil–foundation–building system in high-rise construction. The study is based on a comparative analysis of classical, two-parameter, semi-continuum and continuum subsoil models, including the Winkler, Pasternak, Filonenko-Borodich and Vlasov models, as well as spatial finite element formulations. A unified notation system is used to describe settlements, contact pressure, angular distortion and additional axial forces caused by differential foundation deformation. It is shown that differential settlements and angular distortion are the key engineering indicators for high-rise buildings, since they directly affect the redistribution of forces in columns, walls and other vertical load-bearing elements. A staged modelling procedure is proposed, in which preliminary assessment is followed by refined analysis and subsequent spatial verification of the entire system. An integral suitability index is used for preliminary comparison of raft, pile and piled-raft foundation systems. The practical value of the study lies in formalising the transition from simplified analytical models to detailed spatial analysis and reducing the risk of design decisions in which the structural consequences of differential settlements are underestimated.

Determination of the resistance of a residential building to progressive destruction under serial explosive loading using FEM-technology
type: item
description: The stress state of deformation of building structures of a monolithic reinforced concrete residential block under shelling conditions was simulated using FEM technology in a nonlinear formulation and a conceptual model of the building was proposed that allows avoiding progressive destruction even during successive shell impacts on the most stressed areas of the load-bearing structures. Four FEM models of the building were analyzed: one initial model without damage and three models with the most stressed elements sequentially dismantled. The creation of new models was completed after reaching the stage of destruction of the final elements, i.e. after the beginning of the process of progressive destruction.

Features of reinforcing and repairing building structures after prolonged exposure to moisture
type: item
description: Inspections of buildings and structures are conducted to obtain objective data on the actual condition of building structures, taking into account changes over time. The effect of moisture on structures in contact with the ground leads to a decrease in performance and a loss of strength. At a specific major renovation site, a study was conducted on the condition of brick structures that were subject to constant wetting due to leaks in water supply networks. The condition of the brick structures in contact with the ground, as revealed during demolition work, was found to be worse than that determined by visual inspection. The article presents structural solutions for the restoration of building elements that allow for a reduction in their moisture content over the long term.

Effective design solutions for ventilated facades
type: item
description: The article investigates a cold-formed steel subsystem for ventilated facades, considering the composite action of studs, brackets, and fastening elements. An analytical calculation is combined with numerical modeling to evaluate the structural behavior under service loads and to determine rational variants of its geometric configuration. It is shown that the load-bearing capacity and deformability of the system significantly depend on the profile thickness, support scheme, and the nature of force transfer within the joints. The obtained results confirm the feasibility of a comprehensive design approach to the facade subsystem, in which not individual elements are assessed, but the entire structural system as a whole.

Local stability of soil-cement columns above undergraoud excavations
type: item
description: The paper studies local stability of soil-cement elements (SC) formed by a jet grouting technology within the zone influenced by underground excavation. The research topicality is stipulated by the accident taken place in 2021 during metro construction in the city of Dnipro and the need to assess risks during excavation in strengthened foundations. The aim of the study is to determine the influence of the geometric parameters of SCs and reduction of their strength on the stability of rock mass above the excavation. The conditions of the accident development are analyzed, including hydrogeological regime, dynamic loads from drilling-and-blasting operations, and disturbance of soil structure. It is defined that deviations of the SC dimensions from the design values and a decreasing strength along the SC lateral surface significantly reduce the excavation roof stability. A considerable influence of dynamic loads on stability loss is confirmed. Practical recommendations are formulated to improve the reliability of geotechnical systems and reduce accident risks.

Automation of Calculations of Steel–Concrete Composite Structures in the TechEditor Software Environment
type: item
description: This paper addresses the automation of steel-concrete composite structure analysis within modern digital environments. The authors substantiate the necessity for flexible engineering tools that combine high accuracy, computational efficiency, and cost-effectiveness — factors that are critically important for the reconstruction of Ukraine’s infrastructure under limited resource conditions. The aim of the study is to develop and implement a computational methodology for steel-concrete composite beams within the TechEditor environment, integrating classical analytical approaches of structural mechanics with numerical modeling via the Finite Element Method (FEM). The research methodology utilizes transformed section properties and a step-by-step determination of the stress-strain state. The proposed approach combines the precision of analytical relationships with the flexibility of FEM, which is used to determine internal forces and deflections under realistic boundary conditions. A key feature of the methodology is its transparency, which eliminates the “black box” issue typical of proprietary commercial software, ensuring full control over the calculation logic and unit consistency at every stage. To demonstrate the capabilities of this parametric approach, a finite element model was developed to investigate the variation of the cross-section utilization factor and relative beam deflections for slab thicknesses ranging from 30 to 150 mm. The validation results confirm that implementing parametric relationships enables rapid optimization of design solutions and reduced material consumption without compromising structural reliability. The resulting digital solution, presented as an interactive report, ensures high accuracy and transparency while significantly improving design productivity and reducing the risk of human error.

Research on the prospects for obtaining iodine from carbohydrate fields in Ukraine
type: item
description: The article describes that industrial waters are limited to deep parts of heavy hydraulic structures, mainly in zones of slow and very slow water exchange. It has been established that the production of iodine from reservoir waters is profitable under the condition that its concentration in the water is 18 mg/l. It is described that the concentration of iodine in formation waters of the Poltava region is 15-115 mg/l. Based on the results of water sample analysis, it was determined that the waters of the Andriyashiv gas condensate field have an iodine content of 15 mg/l or more. Water with an abnormally high iodine content of up to 115 mg/l was found among the samples of the Chizhivka field, the Rudivka gas field, the Lyman, and the Reshetnyaky oil and gas fields. It was determined that the specific gravity of the waters of the gas fields is usually low - from 1.071 to 1.085 g/cm3, and the water of the Reshetnyaky field is high - from 1.132 to 1.167 g/cm3. Formation waters of the following deposits were studied: Mashivka; Chutove; Raspashnivka; Novoukrainske; Lanna; Western Khrestyshche; Chervonoyarske; Western Starovirivske; Vedmedivka; Efremivka; Western Efremivske; Western Sosnivka; Kegichivka; Shebelinka from the intervals from 2520 to 5560 m. It was found that the mineralization of formation water was from 33.0 to 337.01 g/kg, the iodine content from 13.5 to 54.74 mg/l. It can be argued that the formation of groundwater with a high iodine content was significantly influenced by the considerable thickness of the sedimentary strata and the corresponding thermobaric conditions.
