楼梯作为结构的一种支撑,对结构的整体性能有着重要影响.以实际工程为背景,采用ETABS软件建立了考虑楼梯构件和不考虑楼梯构件两个钢框架模型,分析了在地震作用下楼梯构件对钢框架结构整体受力性能的影响.计算结果表明,楼梯构件作为一种支撑,具有较大的刚度,对结构的周期、振型、层剪力和层间位移都有很大的影响,必须合理布置楼梯,分析中应考虑其影响,设计中应加强重视.

@@@@The stairs ,as a support of the structure ,have an important impact on the overall performance of a structure . Here ,taking a project as background ,two steel frame models of considering the stair component or not are set up based on ETABS software ,and the impact of the stair component on the integral forced performance of steel frames is analyzed under seismic action .The results show that the stair component as a support has greater stiffness .It has a significant im-pact on the period ,mode ,floor shear ,and inter story drift of the structure .The stair arrangement must be reasonable . The impact of the stairs should be considered in analysis ,and should be more emphasised on design .
