Abstract: Seismic analysis including spectrum analysis and elastic time-lustory analysis completed with the large-finite analysis software-ANSYS was introduced. Correlative theory, step and keypoints were discussed. One prestressed complex steel structure with cable is representative of a group as a whole, main order and typical results of analysis are offered in order to provide some assists to the other seismic analysis of similar structures.
Keywords: seismic analysis; spectrum analysis; elastic time-history; ANSYS; prestressed cable
