钢排架地震作用响应谱分析计算

Analysis and calculation of seismic response spectrum of steel bent

以某水库坝顶启闭机闸房为研究对象,对钢排架在地震作用下的计算方法选取、模型简化、工况分析进行论述,利用ANSYS Workbench模块计算模态和地震响应谱,获得钢排架在地震作用下的最大响应、结构的位移和应力均有所增加、但地震响应不是该钢排架设计的控制载荷的结论。

Taking the gate sluice of a reservoir dam as the research object,this paper discusses the calculation method selection,model simplification and working condition analysis of the steel bent under the action of earthquake.And the modal and seismic response spectrum are calculated using the ANSYS Workbench module.The conclusion shows that the maximum response of the steel bent under the action of earthquake,the displacement and stress of the structure have increased.And the result shows that the seismic response is not the control load of the design of the steel bent.
