[摘要]深圳地铁汇通大厦采用钢筋混凝土框架-核心筒双重抗侧力体系,外围框架柱底部24层采用型钢混凝土柱;工程西侧裙房为20m大跨结构,东侧裙房悬挑为10m,塔楼北侧7~13层设置斜柱。介绍项目的结构体系、结构整体设计指标,并对多程序的计算结果进行分析对比。整体结构及构件设计融入了性能化设计思想,主要抗侧力构件满足中震不屈服(关键构件在中震作用下保持弹性)的设计目标,对W形钢管柱、空腹桁架、斜柱受力进行了细致分析,并对结构进行大震作用下的动力弹塑性时程分析,结构各项指标满足抗震性能化及规范的要求。

Abstract:Shenzhen Metro Huitong Building is an out-of-code high-rise building. It adopts the dual lateral resistance system of reinforced concrete frame-corewall system with steel reinforced concrete columns adopted in peripheral frame columns in bottom 24 layers. The project′s podium on the west side is a 20m large-span structure, and the podium on the east side has 10m suspension, and inclined columns are set between 7~13 layers of the north side of the tower. The structural system and the overall design indices of the project were briefly introduced and the calculation results of different programs were analyzed and compared. Performance-based design theories were integrated into designs of overall structure and components and the main lateral resistance components met design objectives of not yielding under fortification earthquake, that is, key components keeping elastic under fortification earthquake. The mechanics of W-shaped steel tube column, the vierendeel truss and inclined columns were analyzed in detail, and the dynamic elastic-plastic time-history analysis was carried out on the structure under the rare earthquake. All the indicators of the structure met the requirements of performance-based seismic design and the specifications.

Keywords:super high-rise building; steel reinforced concrete column; performance-based seismic design; dynamic elastic-plastic analysis; buckling analysis; W-shaped steel column
