DUCTILITY DEMAND OF BEAMS AND JOINT PANELS IN STEEL MOMENT FRAMES

Abstract

This paper presents the method for the prediction of seismic damage on beams and joint panels in steel moment frame. In this method, the maximum and cumulative plastic deformation of beams and joint panels are estimated on condition that input energy into the system is known. The earthquake response analyses of fishbone-shaped frame are carried in order to evaluate the applicability of the proposed method. Comparing the results of the prediction and the analysis, it is found that the results of the prediction are in good agreement with the average of the results of the analysis.
