摘要：

This paper presents an automated method for derivation of capacity curve from measured structural acceleration response. Based on the decomposition by wavelet transform method, the structural behavior is directly evaluated in the form of a capacity curve of the predominant response, as a relationship between the spectral force and spectral displacement. It enables the user to judge the performance of the building quickly after an earthquake. The feasibility of the proposed method is demonstrated through numerical simulations, full-scale shaking-table tests, and actual response of a steel tower during 2016 Fukushima earthquake.
