SEISMIC RESPONSE PREDICTION OF STEEL FRAMES UTILIZING PLASTIC STRAIN ENERGY OBTAINED FROM PUSHOVER ANALYSIS
A seismic response prediction method for building structures presented in this paper is based on the energy balance concept, which can predict maximum inter-story drift and damage of each member of buildings. In this paper, the procedure of seismic response prediction for steel moment-resisting frames is illustrated, which is utilized inelastic strain energy obtained from pushover analysis. In order to examine the validity of the proposed method for practical application, thirteen kinds of example moment-resisting steel frame were selected. A series of earthquake response analyses of these example frames was carried out, and was compared to the results of the proposed method. From the results of the earthquake response analysis, it was found that the maximum inter-story drift and the cumulative ductility demands of members obtained from the proposed method could approximately catch the tendency of results of the earthquake response analysis.
