The paper considers the formation of new industrial cities in West Siberia of the First Five-Year Plan (1928-1932) during the interaction between regional conditions and architectural and town planning activity. The purpose is to identify regional features of the architectural and urban environment in West Siberia. A comparative analysis of archival materials of the late 1920s and early 1930s is presented for the formation of new West Siberian cities, namely: Novosibirsk, Barnaul, Kemerovo, Prokopyevsk, and Novokuznetsk. The comparison of Novosibirsk, Barnaul and Kuzbass cities shows general and specific features of the cities. The analysis of archival materials shows that regional architectural and town planning features in West Siberia of the First Five-Year Plan have been formed during the interaction of the departmental approach and regional conditions. In Novosibirsk and Barnaul, this interaction was organized by the regional authorities. On the contrary, in Kuzbass cities this process was uncontrollable and resulted in emergence of new problems of town planning.

The paper presents the physical model of the dynamic deformation of reinforced concrete. The model is constructed on the basis of research and generalized experience of national and international research. The model considers such factors as the rate of deformation, confinement reinforcement, crack formation affecting strength properties of the reinforced concrete, concrete resistance by crack edges, driftbolt effect, and others.

The paper presents a discrete model of masonry based on destruction mechanisms deduced from experiments and developed considering the contact interaction between base materials using interface elements introduced into the model. The proposed system of masonry strength criteria corresponds to biaxial stress state conditions, while design technology allows considering the structural modification of the model. Verification of the modeling technique and design technology is based on comparison of experimental results that allow the determination of the key role of elements providing the interaction of base materials during the elastoplastic deformation of masonry. The suggested discrete model of masonry and design technology cane be used in detailed examination of elastoplastic properties of piecewise homogeneous composites.

The paper presents results of experimental research carried out into the static bending of reinforced laminated beam. The beam is reinforced with carbon tape placed in the two interlamellar bottom layers. Tests were carried out on a hydraulic press. Deformations and displacements online measurements are provided by the VIC-3D digital optical system based on the principle of correlation between digital stereoscopic images. Linear and shear strains are determined with the frequency of 1 Hz. The obtained images of the stress distribution of the visible beam surface reflect the stage of elastic and elastoplastic deformation. The possibility of using the VIC-3D digital optical system for determination and destruction of laminated beams is shown in this paper.
