| 摘 要： | 对实际工程中出现的大跨旋转楼梯,普通设计计算方法已经不能满足对建筑以及结构等方面的要求.利用有限元结构分析软件进行结构振动分析计算,以得到结构动力特性,了解结构整体力学性能,并得出采用扁钢作为踢板可以有效地提高结构的整体刚度,从而避免结构晃动过大,增加了舒适度.为相关工程提供一定的参考.

| Abstract: | For the large-span spiral stairs,the normal calculation method is no longer to satisfy the request of architecture and structure.The finite element method can get the dynamic characteristics to help understand the mechanical properties.A conclusion of using flat steel as the kick plate can improve the stiffness of spiral stair effetively and help to avoid the sloshing,so as to offer the reference to the relevant engineering. |
