Abstract: The authors proposed a seismic design method based on static analysis to steel 1-story portal frame bridge piers. The method uses the equal-energy principle and correction functions proposed by the authors to estimate the maximum response displacement. The residual displacement is predicted by the estimation formulae proposed by Usami et al. In this study, the applicability of the method to 2-story frames is examined by carrying out pushover analysis and dynamic response analysis for ten models. It was shown that the method can be also applied to 2-story frames,but the estimation accuracy of residual displacement should be improved.
