Design of Earthquake-Resistant Buildings. New Generation Standards

Abstract

In modern practice of designing buildings in seismic areas, there is a constant increase in the level of detail of models, however, calculations often ignore the fact that seismic impact is a random process with large variability of parameters, and the interaction of the structure with a nonlinearly deformable foundation is not always taken into account correctly. In addition, when calculating seismic impacts, it is necessary to use modern material models that take into account the nonlinear nature of deformation under cyclic loads. All the factors described above indicate the need to develop complex methods for calculating seismic impacts. The article describes an integrated approach to the calculations of buildings and structures being built in seismic areas, and also provides the main theses for the STO “Construction in seismic areas. Basic provisions”. The section “materials used and research methods” presents the key components of the proposed methodology (nonlinear calculation method, material models and foundation model). The section “research results” presents the main provisions of the proposed two-level calculation. In conclusion, it was concluded that it is necessary to update modern standards and methods of calculation for seismic impacts.
