摘要
介绍了一拱形钢棚在冰雪荷载作用下坍塌的情况,对其主要构件进行了强度和稳定性验算,分析了钢棚坍塌的原因,最后对存在的一些问题进行了总结。
An arched steel-canopy which was collapsed under the snow and ice load is introduced. The strength and stability of the main component are checked and the reason of the collapse is analyzed. Finally, the problems of the design are summarized.
