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作者簡(jiǎn)介：趙變青，工程師，Email : 13934602004@163.com。參考文獻(xiàn)［1］GB 50223—2008建筑工程抗震設(shè)防分類(lèi)標(biāo)準(zhǔn)［S］. 北京：中國(guó)建筑工業(yè)出版社，2008.［2］GB 50011—2010建筑抗震設(shè)計(jì)規(guī)范［S］. 北京：中國(guó)建筑工業(yè)出版社，2010.［3］GB 50009—2012建筑結(jié)構(gòu)荷載規(guī)范［S］. 北京：中國(guó)建筑工業(yè)出版社，2012.［4］JGJ 3—2010高層建筑混凝土結(jié)構(gòu)技術(shù)規(guī)程［S］.北京：中國(guó)建筑工業(yè)出版社，2011.［5］路江龍，楊律磊，龔敏鋒，等. 太原國(guó)海廣場(chǎng)主樓罕遇地震彈塑性時(shí)程分析 ［J］. 建筑結(jié)構(gòu)，2014，44（21）：42-46,74.
