Numerical modeling of influence of defects and damages on bearing capacity of building structures

Abstract

According to the Russian building codes, the numerical study of structures should be carried out taking into account the existing defects and damages. On the example of a U-shaped reinforced concrete frame containing damage, a comparative analysis of three cases of stress-strain state was carried out in comparison with the design scheme without damage. Also, a library of typical damages of reinforced concrete columns and proposed design models was compiled. The calculations were performed by the finite element method in LIRA-SAPR.
