The main building adopts mixed structural system of concrete filled steel tubular frame-reinforced concrete core wall with five belt trusses along the height of the structure. Several structural schemes were compared in design. Performance-based seismic design method was adopted considering multiple out-of-code indicators. Several programs were used to analyze the whole structure and part of the structure, including elastic time-history analysis and response spectrum analysis under frequent earthquake, seismic performance calculation under medium earthquake, elastic-plastic time-history analysis and performance evaluation under rare earthquake, slab stress analysis of typical floor and the numerical analysis of key joint bearing capacity. The calculation results are capable of achieving the expected seismic performance objectives.Keywords:mixed structure; belt truss; performance-based design; slab stress; joint bearing capacity作者简介：赵变青，工程师，Email : 13934602004@163.com。参考文献［1］GB 50223—2008建筑工程抗震设防分类标准［S］. 北京：中国建筑工业出版社，2008.［2］GB 50011—2010建筑抗震设计规范［S］. 北京：中国建筑工业出版社，2010.［3］GB 50009—2012建筑结构荷载规范［S］. 北京：中国建筑工业出版社，2012.［4］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.［5］路江龙，杨律磊，龚敏锋，等. 太原国海广场主楼罕遇地震弹塑性时程分析 ［J］. 建筑结构，2014，44（21）：42-46,74.
