【摘要】 利用有限元分析软件ETABS对考虑楼梯作用的平面不规则框架进行计算,并与不考虑楼梯作用的框架作对比,分析了在地震作用下楼梯对框架的刚度、位移、内力的影响,着重分析了楼梯构件的受力状况,提出了结构设计时的注意事项。更多还原

【Abstract】 Two complex-planar frames,with and without consideration of staircase effect were analyzed and compared by using ETABS.The influences of staircases on the structural rigidity,story drifts and inner forces of the frame system under earthquakes were investigated.Load conditions for structural members associated with staircases,in particular,were studied.Some suggestions were proposed for staircase design based on the analysis results.更多还原
