[摘要] 深圳证券交易所是国内罕见的巨型悬挑超高层建筑。采取合理的结构设计使传统的正交桁架具备足够的冗余度；通过研究对比，有异于传统直观判断而确定桁架形式；详细分析超大型桁架节点的工作状况；采用特殊的施工顺序，“抗”“放”结合优化结构受力；创新性的研究并实施应对大悬挑钢结构混凝土楼盖受拉裂缝控制的手段；研究钢梁．混凝土组合楼盖框架梁侧向支撑设计，提出在一定条件下梁下翼缘稳定控制的实用设计；并实施全面的健康监测。

Abstract: The building of Shenzhen Stock Exchange is the long cantilever super high-rise building that was seldom found domestically:traditional orthogonal truss has enough redundancy by reasonable structural design; determinats truss form by comparuon different from traditional method; detailed analysis the stress of the super large truss joint; takes special construction sequence and optimizate structure stress based on resistance and discharge; takes a innovative method to avoid the concrete floor to crack in long cantilever area; takes a method to stability control the bottom flange of the frame beam in composite floor; takes comprehensive health monitoring.
Keywords: long cantilever; super high-rise; trussed tube; super large truss joint; knee brace; back stationary
