摘要
介绍了实际工程中钢结构螺旋楼梯结构体系的选型过程,针对螺旋楼梯形状不规则、结构传力不明确所产生的复杂计算问题,通过有限元软件ANSYS建立分析模型,采用3种不同的荷载工况模式分别对该螺旋楼梯进行了静力分析,同时应用人行激励荷载对模型进行了舒适度分析。分析结果表明,复杂螺旋楼梯主要由整体刚度来控制结构的安全性。
The paper introduced the selection process of steel spiral staircase structure system of a project. According to the complicated calculation problems of irregular shape for the spiral staircase,and the structure of force was not clear,the analysis model was established through the finite element software ANSYS. Three different loading modes were applied respectively on the spiral staircase to conduct static analysis,and the comfort degree of the model was analyzed by using the pedestrian excitation load. It is believed that the complex spiral staircase mainly controls the safety of the structure by the overall stiffness.
