Abstract

Reinforced Concrete Beam Column joints are most vulnerable regions of any reinforced concrete (RC) structures. The performance of reinforced concrete joints determines the performance of whole building during seismic loading. Many researchers have focused on the experimental study of RC joints to determine the seismic performance of RC structures. However, experimental tests are expensive and time consuming. Therefore, the alternative approach of numerical modeling is preferred to study numerous factors that affects the response of beam-column junctions. This paper reports on the macro modeling of RC beam-column junctions with a finite element (FE) software, SeismoStruct. The outcomes of experimental and finite element (FE) model outcomes are compared and found to be in excellent agreement. For the FE model, ultimate load capacity was 75.2 KN. This numerical load capacity was higher than the experimental test by about 8%, and the corresponding drift ratio at which the numerical load capacity was achieved was 4.33%. The drift ratio value of numerical model was found to be 2% higher than that of experimental model. The mechanisms responsible for the nonlinear behavior of RC joints, including bar slip and shear panel failure can be incorporated and studied using this simplified numerical macro model.
