| Abstract. | Problem statement. The acceleration of technological changes and the increase in requirements for the efficiency and reliability of structures in the 21st century require a revision and improvement of methods of structural mechanics. In addition, the study of the deformation processes of materials such as concrete, graphite, polymers, (rocky) soils and others has shown that their mechanical behavior differs in many ways from traditional concepts. Thus, the development of new reliable computational models describing the behavior of such materials is becoming increasingly relevant. The purpose of the study is to develop an improved method of strength analysis based on finite element calculation of combined systems in the form of a building on a multilayer elastoplastic base. The sensitivity of the physical and mechanical characteristics of materials to the type of stress state, the development of plastic deformations in the reinforcement, damage, induced heterogeneity, cracking are taken into account. The objective of the study is to obtain quantitative estimates and to compare the results with other common methods of determination of the stress-strain state of a reinforced concrete residential building located on a base of several layers of rocky soil, taking into account a complex of loads including seismic and wind impacts. Results. A new method for calculating combined “building-base” systems has been proposed, using new theoretical approximations for deformation diagrams of rocky soils. The developed flat hybrid finite element has been fully described. The stress-strain state of combined “building-base” systems under various loads has been calculated according to current regulations for special load cases. Conclusions. It has been shown that accurate calculation of the mechanical behavior of materials is crucial for obtaining an accurate forecast of the stress-strain characteristics of the “building-base” system under complex load conditions. The reliability of the obtained results was assessed by comparison with calculations in modern software packages and simplified theories. |
