Abstract
This paper discusses the methods to compare the relationship between the strong motion indices and damage of structures. Based on the rank correlation analysis for the dynamic analysis results, it is pointed out that the correlations could change depending on the damage levels and the structural periods. In the nonlinear time history analyses, the responses of wooden structure models of Single-Degree-of-Freedom (SDOF) were simulated for nine hundred input motions. It is observed that the responses of the linear SDOF systems with 20% damping ratio and with elongated periods, considering the damage thresholds, show fairly good correlation with the damages.
