摘　　要：深圳科技生态园四区工程由两栋超高层塔楼、9层裙楼和3层地下室组成。其结构具有多项不规则、塔楼超B级高度、裙楼大底盘不设缝和西北角35m大跨度悬挑等特点。从结构体系上剖析塔楼、裙楼及整体关系,就工程特点进行结构性能化设计、大底盘温度作用分析及大悬挑专项分析论证。整体性能化分析表明,结构能实现拟定的性能目标,此外单塔与双塔抗震性能结果相近。重力荷载与温度作用的非线性分析结果表明,受力较大部位主要是大跨支座部位与塔楼范围,设计时应予以适当加强。有限元分析结果表明,人字形托柱桁架不仅能满足承载能力的要求,也能满足正常使用状态的要求。The project in No. 4 Area of Shenzhen Ecological Science Park includes two super high-rise towers,a nine-floor podium and a three-floor basement. The structure has features such as multiple irregularities, height over B-level requirement of the code,large base podium without joints and 35m-span cantilever in northwest part. The characteristics of towers,podium and mutual relations were introduced in perspective of structural system. Performance-based structural design,temperature effect analysis for the large base podium and large-span cantilever analysis were carried out according to the project characteristics. Integral performance-based analysis shows that the structure can reach respected performance goals and seismic performances of the single tower and double towers are similar. Results of nonlinear analysis under temperature action and gravity load show that parts with large stress mainly distribute in large-span bearings and towers,which should be appropriately strengthened. Finite element analysis results show that the supporting column transfer truss with the herringbone shape can meet the requirements of carrying capacity and normal operating condition.
