【摘要】 新版抗震规范强调了楼梯对于结构的重要性,为了分析楼梯对框架结构抗震性能的影响,应用MIDAS/Gen软件通过对比有无楼梯参与整体结构计算分析,得到了楼梯对整体结构自振特性结构整体反应,以及楼梯构件自身的地震响应。由此更准确地得出地震作用下结构与构件的破坏部位及形式,也对结构设计及加固工作具有参考作用.更多还原

【Abstract】 The new seismic code emphasizes the importance of stairs to structure,to analyze the effect of stairs on the seismic performance of frame structures,taking application of MIDAS/Gen software by comparing the calculation and analysis of the whole structure has no participation stairs,got the stairs on the natural vibration characteristics of the structure response of whole structure,and its earthquake response of staircase components.Thus come to more accurately that the damage parts of the structure components and forms under action of earthquake,it also can provide reference for the structural design and reinforcement work.更多还原
