| Outline of Final Research Achievements |
There are large uncertainties in estimating the peak nonlinear response displacement of structures by typical seismic intensity measures. A seismic intensity measure based on seismic energy considering nonlinear response was proposed in this study. It was shown that the proposed intensity measure has better agreement with the peak nonlinear response displacement of reinforced concrete bridge columns.
