摘要
曲线螺旋楼梯因其造型优美而常被建筑师用在高档建筑之中,但从结构受力上来说螺旋楼梯比传统直线型楼梯复杂,内力计算难度有所加大,尤其是楼梯的边界约束条件对楼梯的计算结果影响不可忽视。目前对于螺旋楼梯的计算可以通过表格法进行手动计算,或通过PKPM、理正以及其他有限元软件进行计算。本文通过对悬挑螺旋楼梯与普通螺旋楼梯基于壳单元的SAP2000程序对比,指出悬挑螺旋型楼梯在结构设计中应注意的问题,以供大家参考。
As the elegant of spiral stairs,it's often used by architects in top-grade buildings,but the difficulty of its internal force calculation is increased which compared with the traditional linear stairs,especially the effect on the internal force calculation results caused by constraints in the boundary of stair cannot be ignored. Now for obtain the internal force of the spiral staircase,it can use table method for manual calculation or by PKPM,Lizheng and other finite element software to calculate. This article through compare the difference of internal force between the cantilever spiral staircase and ordinary spiral staircase by SAP2000 software which based on shell element to find out the problems,which should be paid attention to the design process and give the reader as a reference.
