Vol. 2 No. 65 (2025): ACADEMIC JOURNAL Industrial Machine Building, Civil Engineering

This issue presents the results of scientific and applied research in the fields of construction engineering and mechanical engineering. The papers address the study of the stress–strain state and strengthening of reinforced concrete structures, in particular floor slabs and beams, as well as technologies for the rehabilitation and reconstruction of existing buildings. The issue also considers numerical modeling of structural behavior, investigations of the bond between reinforcement and concrete, the performance of concrete shear key connections, and approaches to ensuring the reliability of buildings and structures.

Special attention is given to modern construction technologies, particularly the use of 3D printing of concrete elements and the application of 3D-printed permanent formwork. The issue also highlights challenges related to urban renovation and building modernization, the assessment of secondary construction waste, and the design of civil protection shelters. In addition, the papers address modeling of noise propagation in urban environments, the use of geodetic drones for three-dimensional mapping, and studies of equipment for the preparation and transportation of construction mortars.
