摘要：
In the incremental dynamic analysis (IDA), the intensity of one single ground motion is increasingly set according to a series of intensity measures(IMs). The elasto-plastic dynamic analysis of the structure under different IMs is then carried out to obtain the relationship between the structural damage measure (DM) and ground motion IM. When considering a set of ground motions, the analysis of DM-IM curves can be applied to the evaluation of the structural performance. IDA is thus seen as the so-called "dynamic pushover analysis". The paper presents an introduction of the method of IDA and its application to a hybrid structure. The analytical process and results are helpful for the performance-based seismic design of hybrid structures and a wide application of IDA in complex structures.
