Abstract

In this paper, evaluation method of "collapse limit displacement" of RC buildings based on seismic response spectrum was proposed. The method is more practical approach to evaluate collapse limit displacement than previous method based on dynamic analysis. Collapse limit displacement estimated by the method was compared with dynamic analysis of simulated and observed ground motion in past. The results showed good agreement with dynamic analysis. However, cases that natural period of model equal to 0.2sec showed large dispersion. In addition, it was clarified that capacity degradation curve affects to collapse limit displacement.
