［摘要］中華國(guó)際廣場(chǎng)主體結(jié)構(gòu)高度為132.5m，采用鋼筋混凝土框架-剪力墻結(jié)構(gòu)體系，主樓南側(cè)1～14層采用斜柱單跨框架，與豎向框架-剪力墻結(jié)構(gòu)單元自9層相交至14層完全成為一個(gè)整體。主體結(jié)構(gòu)存在扭轉(zhuǎn)不規(guī)則、構(gòu)件間斷、承載力突變、斜柱等不規(guī)則項(xiàng)，屬于多項(xiàng)超限結(jié)構(gòu)。介紹了結(jié)構(gòu)的基本構(gòu)成體系、超限的具體項(xiàng)目及采取的措施、抗震性能化設(shè)計(jì)目標(biāo)的確定及實(shí)現(xiàn)。采用ETABS有限元軟件和PMSAP設(shè)計(jì)軟件進(jìn)行了小震彈性分析、中震彈性分析以及大震的彈塑性分析。結(jié)果表明，結(jié)構(gòu)受力性能良好，能夠滿足相應(yīng)的抗震性能目標(biāo)。詳細(xì)研究了核心筒偏置對(duì)結(jié)構(gòu)抗震設(shè)計(jì)的影響及對(duì)策。最后分析了中震彈性下樓板的應(yīng)力和斜柱與垂直柱交叉節(jié)點(diǎn)的應(yīng)力。結(jié)果表明，樓板應(yīng)力滿足中震彈性工作狀態(tài)的要求；梁柱節(jié)點(diǎn)處存在較大的應(yīng)力集中，采用強(qiáng)節(jié)點(diǎn)連接設(shè)計(jì)進(jìn)行了加強(qiáng)。

Abstract: Zhonghua International Plaza is a super high-rise building with the height of 132.5 meter, which is reinforced concrete frame-shear wall structure system. From the first floor to the 14th floor, it is single span frame structure with inclined column  in the south of main building. The single span frame structure intersects with the vertical frame-shear wall structural unit from the 9th floor to the 14th floor and completely becomes a whole. And the main building is a out-of-code structure on many aspects, including torsion irregularity, component discontinuity, bearing capacity mutation, inclined column and so on. The basic system of the structure, the specific out-of-code aspects and  measures taken,and the determination and realization of performance-based seismic design objective were introduced. Moreover, the elastic analysis of small earthquakes, elastic analysis of moderate earthquakes, and elastoplastic analysis of large earthquakes were analyzed by ETABS finite element software and PMSAP design software. The results show that the structure’s mechanical performance is well and corresponding seismic performance objectives are satisfied. The influence of the core tube offset on the seismic design of the structure and its countermeasures were studied in detail.Finally, the floor stress in moderate earthquake and the stress in the intersection node of inclined column and vertical column were analyzed. The results show that the floor stress meets the requirements of elastic working state under moderate earthquake. There is a large stress concentration in the beam-column joints, which is strengthened by the strong joint design. 

Keywords:frame-shear wall structure； out-of-code high-rise structure； performance-based seismic design； elastoplastic analysis； stress analysis
