冰雪灾害下某排架结构钢屋面受损案例分析

Case analysis of a steel roofing in bent structure damaged by the ice and snow disaster

近几年我国各地发生较大的冰雪灾害,导致钢屋面暴露较多的结构安全问题,给社会带来严重的损失,因此研究冰雪灾害下钢屋面受损显得尤为重要。通过一起冰雪灾害下某排架结构钢屋面受损的工程实例,分析了受损构件的破坏特征和原因,提出了针对性整改措施,为避免轻钢屋面在冰雪灾害下的破坏研究提供了重要的工程价值。

In recent years,large ice and snow disasters have occurred in various parts of China.It resulted in a lot of structural safety problems caused by steel roofing,which has caused serious losses to the society.It is particularly important to study the damage of steel roofing under the ice and snow disaster.This paper analyzes the damage characteristics and causes of damaged members through an actual engineering example of a steel roofing in bent structure damaged by the ice and snow disaster.Some pertinent rectification measures are put forward to provide important engineering value for the research of avoiding the damage of light steel roofing under the ice and snow disaster.
