【摘要】 学校建筑属于特殊的公共建筑,学生密度相对较高、活动频繁、流动量较大,所以有必要研究学校建筑的抗震性能。本文利用SAP2000有限元分析软件分析考虑梁式楼梯参与结构整体计算时的结构固有特性及结构的地震作用响应,与传统楼梯设计方法(楼梯间结构不考虑地震作用,结构处楼梯间开洞)结构地震反应做对比。结果表明:考虑楼梯参与结构整体计算会增加结构的抗侧刚度,且结构扭转效益增大,总体对结构不利。更多还原

【Abstract】 School buildings are unique public buildings,the relatively high density of students,activities,frequent large flows,it is necessary to study the seismic performance of school buildings.In this paper,finite element analysis software SAP2000 to consider the overall structure of the stairs in the structure calculation and structure of the inherent characteristics of seismic response,with the traditional design method of stairs(staircase structure is not considered earthquake,the structure at the stairwell openings)seismic response To do comparison.The results showed that: the whole structure into account in calculating the stairs will increase the lateral stiffness of the structure,increase efficiency and torsion,the overall structural disadvantage.更多还原
