The analysis model of the new China Science and Technology Museum is built in CANNY, so as to simulate the pre-stressed structure, spatial composite structure and reinforced concrete structure accurately. The dynamic elastoplastic time-history analysis of the structure is completed by using CANNY as well. It is the first time to do such a large scale dynamic elastoplastic analysis in China. The results indicate that, the elastoplastic displacement is far less than the Code linut, and the earthquake energy is mainly dissipated by the structural damping. Thus, the new China Science and Technology Museum has enough energy dissipation capacity and safety reserve under rare earthquake.Keywords: CANNY; complex structure; nonlinear; elastic-plastic; dynamic
