| Outline of Final Research Achievements |
The purpose of the present research is to establish effective design procedures for bridges with seismic response modification techniques, namely seismic isolation and energy dissipation device application. Firstly, the bi-directional character of input seismic ground motion acceleorograms is analyzed and efficient numerical procedures to generate spectrum-compatible bi-directional input accelerograms are developed. Secondly, methods for modeling of the bi-directional nonlinear restoring force characteristics and bi-directional dynamic response behavior are proposed. The combination of these two findings and methodologies are demonstrated to be applicable to seismic performance assessment and damage evaluation of structures with seismic protective measures.
