轻钢结构在雪荷载影响下的灾害原因调查与分析

Damage Investigation and Analysis of Lightweight Steel Construction under the Influence of Snow Load

通过对部分轻钢结构房屋因屋面积雪发生坍塌的破坏情况的调查,选取典型建筑进行结构复原和建模分析,从结构体系、平面布置、构造措施及施工质量等方面详细论述破坏形成原因,并对同类建筑防范罕遇荷载垮塌事故提出措施和建议。

In this paper,the structural recovery and modeling analysis of the typical buildings were selected through the investigation of the collapse of partially light steel structures due to the collapse of the roof snow,and discussed the causes of damage formation in detail from the aspects of structural system,plane arrangement,structural measures and construction quality,and put forward measures and suggestions for similar buildings to prevent the collapse accidents.
