Accumulation of damage in reinforced concrete elements under cyclic loads

Abstract

The article presents the results of research on the behavior of a frame structure in a reinforced concrete building with a full rigid frame under cyclic load typical for strong earthquakes. When creating a finite element model for the research, the models of materials were used that take into account the nonlinear nature of the structure behavior, as well as the accumulation of damage under cyclic loads. The calculation was carried out by a direct dynamic method using explicit schemes for integrating the equations of motion in the multipurpose finite element software package LS-DYNA.
