福建兴业银行大厦搭接柱转换结构有限元分析和预应力策略

FEM Analysis of Lapping Column Transfer Structure and Prestress Strategy in Fujian Industrial Bank Building

深圳福建兴业银行大厦采用了新颖的搭接柱转换结构 ,为了验证搭接柱转换的可靠性和受力性能 ,设计过程中进行了 1∶5的搭接柱破坏试验。用SAP2 0 0 0有限元软件对模型的受力变形进行分析 ,并针对工程采用的主动预应力设计施工 ,进行了设计分析研究。

The new lapping column transfer structure was adopted in Fujian Industrial Bank(Shenzhen) Tower.A 1∶5 scale model collapse test was carried out to investigated the reliability and behavior of lapping column transfer structure.This paper introduced the FEM analysis of the 1∶5 test model structure with SAP2000,including the internal force and deformation.The conclusion from FEM analysis was used to direct the model test and was also validated by the test.Based on the concept of active prestress,research on design and construction of active prestress was presented.
