First of all, the equivalent damping ratio and the number of damping walls were calculated according to the given target displacement. Then the PERFORM-3D program was adopted to perform the time-history analysis under the frequent earthquake level, and the dynamic elasto-plastic analysis under the rare earthquake level as well, both analyses were performed to evaluate the seismic performance of the overall structure. The performance of the critical components was evaluated as well. Meanwhile, the comparative analysis between the energy-dissipated structure and the non-energy-dissipated structure shows that the former structure has capability to undertake greater elasto-plastic deformation and greater strength under rare-earthquakes.Keywords: tall building; energy dissipation; rare-earthquake; dynamic elasto-plastic; performance evaluation作者简介：戴雅萍，硕士，教授级高级工程师，一级注册结构工程师，总工程师，Email:yaping.dai@siad-c.com。参考文献［1］袁雪芬，戴雅萍，张敏，等.宿迁市苏商大厦超限高层结构设计［J］. 建筑结构，2013，43(20): 100-106.［2］南京工业大学建筑技术发展中心. 宿迁市苏商大厦结构消能减震分析［R］. 南京，2011.［3］JGJ 3—2010 高层建筑混凝土结构技术规程［S］. 北京:中国建筑工业出版社,2011.［4］GB 50011—2001 建筑抗震设计规范［S］. 2008年版. 北京: 中国建筑工业出版社, 2008.
