摘要
本文通过调查某低跨钢桁架屋面在雪荷载作用下发生突然整体垮塌事故,分析了钢桁架屋面整体塌落的过程及原因;探讨了设计、施工及构造处理等方面的因素对钢桁架屋面结构构件承载力性能的影响,并提出预防和处理此类事故发生的方法及措施,为类似工程提供借鉴.
The investigation on overall collapsing accident of a low span steel truss roof under snow loads was carried out, and the whole process and reasons of the steel truss roof were analyzed in the paper. Discussing the factors, such as design, construction and structural treatment＇ s affects, which can decrease the bearing capacity of steel roof mere- ber and trusses, the methods and measures of resolving or vide a reference for the similar projects. preventing such accidents were provided. It can also pro-
