既有钢结构旋转楼梯舒适度数值模拟分析

Numerical simulation of comfort improvement of existing steel structure revolving stairs

以某办公楼内既有钢结构旋转楼梯为例,对其进行三维数值模拟,进行既有钢结构旋转楼梯的舒适度分析,并根据分析结果提出了四种改造方案,对比了其改造前后的振动特性。总结了影响钢结构旋转楼梯舒适度的几点因素,为其他工程提供参考。

Taking the existing steel structure revolving stairs in an office building as an example,the paper carries out three-dimensional numerical simulation,analyzes the comfort of the existing steel structure revolving stairs,and puts forward four transformation schemes according to the analysis results,and compares the vibration characteristics before and after the transformation.This paper summarizes several factors that affect the comfort of steel structure revolving stairs,and provides reference for other projects.
