Seismic Damage Index Spectra Considering Site Acceleration Records: The Case Study of a Historical School in Kermanshah

The frequency content and time duration of earthquakes are as effective the peak ground acceleration on structural damage. Therefore, using rapid seismic vulnerability assessment methods that consider earthquake history is noticeable. Kermanshah a historical city generally affected by far-field earthquakes. it necessary to effect low-frequency shocks in evaluating buildings this city. Herein, historic school assumed case study two well-known damage index formulas used for determining spectra structure, considered single degree freedom system. Then, parameters index, including ductility, relative degradation stiffness, dissipated energy determined from nonlinear analysis structure under most probable records. Finally, can be masonry similar sites with various fundamental periods large-scale assessments. result shows building tends collapse at 0.15 g. Furthermore, results confirm resistance reduction flexible floors.
