【摘要】 通过对某框架结构实际工程的分析计算,得到了楼梯对框架结构抗震性能的影响和楼梯自身的抗震特性。结果表明,地震作用下楼梯参与计算时框架结构整体指标和楼梯周边构件内力变化很大,楼梯自身地震反应强烈。根据分析结果,提出了设计建议。更多还原

【Abstract】 Through the analysis and calculation on a frame structure building,the effect of stairs on the seismic performance of the frame structure and the seismic behavior of stairs can be obtained. The results indicate that the overall parameters of the frame structure as while as the internal force of the structural components around the stairs are obviously changed when the stairs are taken into account in the seismic computation. The dynamic response of the stair under seismic action is very intensive. According to the analysis results,this paper provides design suggestions to similar projects.更多还原
