温度荷载对某大型商业综合体项目的影响分析

Influence analysis of temperature load on a large commercial complex project

本工程位于杭州西湖区,其中1#楼为多层大型购物中心,采用钢框架体系结构,平面轴网尺寸达177.8m×103m。单层大面积结构容易受到环境温度变化作用,产生一定变形及温度应力。对该项目在考虑温度应力前后,结构整体计算指标及构件应力产生的变化进行了分析,可为类似工程设计提供参考。

This project is located in the West Lake District of Hangzhou.The 1#building is a multi storey shopping mall,and steel frame structure is adopted.Plane grid size up to 177.8m×103m.Large area structures are susceptible to changes in ambient temperature.The structures will produce certain deformation and temperature stress.This paper analyzes the changes of the overall calculation index of the structure and the stress of the components before and after considering the temperature stress.
