In this paper, to improve seismic response estimation for medium and low-rise RC buildings during aftershock, a hysteresis model which was modified from TAKEDA model was proposed. The modified model was added slip behaviors in loading and unloading processes to TAKEDA model. Time history response analysis using the modified model and TAKEDA model were done to examine the accuracy of the estimated seismic response by comparing with test results. As a result, the hysteresis and period characteristics and the residual displacement calculated by time history response analysis using the modified model were confirmed to give good agreement with experimental data.
