钢结构螺旋楼梯的设计与分析研究

Design and analysis of the steel spiral staircase

针对钢结构螺旋楼梯的复杂力学特性问题,以某商业建筑螺旋楼梯为例,基于MIDAS Gen有限元分析软件,首先设计了三种螺旋楼梯结构方案,而后以结构强度、刚度为基本优化目标,同时考虑建筑结构件舒适度及整体美学效果,确定了最优结构设计方案。结果表明,钢结构螺旋楼梯最优设计方案具有良好的实际应用效果,对类似工程问题的处理具有较好的借鉴意义。

In order to solve the complex mechanical characteristics of the steel spiral staircase, this paper takes the spiral staircase of a commercial building as an example, based on the finite element analysis software of MIDAS Gen, three structural schemes of the spiral staircase are designed, then, taking the structural strength and stiffness as the basic optimization goal, and considering the comfort degree and the overall aesthetic effect of the building structure, the optimal structural design scheme is determined. The results show that the optimal design scheme of spiral staircase with steel structure has a good practical application effect and can be used as a reference for similar engineering problems.
