张江科学之门塔楼结构设计

The Structure Design of ZhangJiang Science Gate Tower

张江科学之门塔楼的主要建筑功能为办公,建筑高度320m,为高度超限的超高层建筑。结构抗风、抗震成为本结构设计的主要问题,为此采用成熟、高效的框架-核心筒结构体系。结构外框柱采用贴合立面的斜柱,既优化了建筑立面效果,也提高的结构的抗侧刚度。设计中采用性能化设计方法、弹塑性时程分析和专项分析(斜墙分析和复杂节点有限元分析)来确保结构的抗震性能和安全性。

The main building function of Zhang Jiang science gate tower is office,which is super high-rise building with the height of320 m.Wind resistance and seismic resistance are the subject matter of structure design.Therefore,the mature and high-efficiency frame-core structure is used.The outer frame column is slant to fit the building faade,which optimize the fa?ade and improves the stiff of the structure at the same time.During the design period,many methods were adopted to insure the anti-seismic property and safety,such as performance-based design,elastic-plastic time-history analysis,and specialized analysis(Analysis of sloping wall and complex joint).
