世茂深港国际中心天环结构敏感性数据驱动优化设计

Sensitivity Data-Driven Optimal Design of the Skywalk Structure in Shimao Shen Gang International Center

敏感性分析可反映设计变量对约束条件的影响程度,应用敏感性数据原理进行结构设计可兼顾结构高效性、设计安全性、工程经济性。简要介绍敏感性数据分析原理,以世茂深港国际中心天环吊挂型长悬挑结构为案例,以竖向挠度和振动舒适度为设计约束,运用敏感性数据驱动钢箱梁和内灌混凝土的优化设计,可供类似项目的结构设计及造价控制参考。

Sensitivity analysis can reflect the influence of design variables on constraints,and the application of sensitivity data analysis to structural design can take structural efficiency,design safety and engineering economy into account.This paper briefly introduces the principle of sensitive data analysis and takes the Skywalk,which is a long-cantilever structure with hung floor in Shimao ShenGang International Center,as a case study.Design constraints of vertical deflection and vibration serviceability are used to drive the optimal design of steel box girders and internally filled concrete using sensitivity data.It can be used as a reference for the structural design and cost control of similar projects.
