张弦梁结构非线性地震响应分析

Study On Nonlinear Seismic Response Of The Beam String Structures

本文以广州国际会展中心单向空间张弦梁结构这一典型张弦梁结构为计算分析算例,应用大型有限元软件AN-SYS对张弦梁结构的地震响应进行了空间非线性时程反应分析,探讨了张弦梁结构在两种不同地震波作用下竖向地震和水平地震响应,得到结构的动位移响应和动内力响应时程曲线。总结出一些有意义的结论,供张弦梁结构的工程应用参考。

Based on the calculation and analysis example of one-way beam string structure in the Guangzhou International Convention and Exhibition Center,large finite element software ANSYS was used for the structure space nonlinear time-history analysis of the beam string structure seismic response.The vertical seismic and horizontal seismic response of the beam string structure under the action of two different seismic wave were discussed,and the dynamic structure and the dynamic displacement response process was obtained.Some significant conclusions for the beam string structure were summarized which can refer to the engineering application.
