Finite element modeling of seismic performance of low strength concrete exterior beam-column joints

Abstract

This paper presents a finite element simulation to capture the nonlinear response of a typical low strength beam-column joint tested at ITU and also results of the finite element modeling and experimental program conducted at KFUPM for beam-column joints in reinforced concrete construction. Finite element analysis is performed using the software DIANA, simulating the concrete response through Drucker-Prager plasticity with a tension cut-off as failure criterion and using for the reinforcing steel Von-Mises plasticity with multi linear isotropic hardening. The failure mode and deformation response of low strength concrete beam-column joints was predicted with a good correlation between the experimental and inite element results.
