Abstract
The aging and durability performance of numerous infrastructures that were constructed during the high economic growth period of Japan constitutes one of the current social issues. In this study, in order to consider the trigger causing a residual displacement considering a large deformation such as the P-delta effect, we investigate the nonlinear earthquake response characteristics using two types of rocking SDOF models (approximate and rigorous (include P-Δ effect)). Furthermore, we have carried out a non-linear response analysis and performed the characteristics extraction of the absolute acceleration wave pattern using the discrete wavelet transform. From these analysis, the triggered residual displacement indicates a predictable relationship between the sum of square accumulation value of the wavelet coefficient and time history of spectrum intensity value.
