For structure characteristic of this project, the performance objectives are identified. Response spectrum analysis elastic dynamic analysis under frequent earthquake and moderate earthquake are conducted, and pushover analysis under rare earthquake is also adopted. For verify the results of analysis, shaking table experiment is introduced. Calculation analysis and model experiment show the overall structural has a good anti-seismic capacity to achieve the scheduled performance objectives.Keywords: irregular structure; seismic design; performance objective; shaking table experiment
