Response of Reinforced Concrete Members Under Seismic Loads

On the basis of material stress-strain relationship established on the results of experimental studies,a theoretical model was developed to predict the behaviors of reinforced concrete structural members under seismic loads. As an application of the model, a computer program, NBAP,was developed to calculate member nonlinear behaviors. The theoretical behaviors of the members calculated by NBAP were compared with the experimental behaviors reported in the literature. It was found that the proposed model gave good predictions for both monotonic and cyclic behaviors in consideration of member stiffness,strength, stiffness and strength degradation,and ductility.
