浙江省台州市某超限高层建筑结构设计

Structural design of a tall building beyond code limits in Taizhou City,Zhejiang Province

对3号楼整体介绍,且对其进行设缝原则分析。着重对3号B塔元整体结构进行小震弹性分析、弹性时程分析、关键构件“托柱转换梁柱”中震弹性以及大震不屈服分析等性能分析、平面薄弱处采用楼板有限元应力分析、大震静力及弹塑性时程分析,针对结构薄弱层给出具体措施。结果表明,预期的抗震性能目标在采取合理的措施后是可以达到的,且结构在地震作用下是安全的。

The overall introduction of the 3#building,and the analysis of its seam principles.For the whole structure of tower 3#B,small seismic elasticity analysis,elastic time history analysis,seismic elasticity in key member“support column transfer beam column”and non-yield analysis of major seismic performance analysis are carried out,the floor finite element stress analysis,major seismic static and elastic-plastic time history analysis are used,and specific measures are given for the weak layer of the structure.The results show that the expected seismic performance target can be achieved after taking reasonable measures,and the structure is safe under earthquake action.
