摘要
为了提高建筑结构的防灾能力,针对我国08年南方冰雪灾害引起的工程事故,本文探讨了建筑结构设计雪荷载的取值问题,分析了屋面高差、屋顶坡度、屋面形状、局部风速对雪荷载的影响机理,提出了建筑结构雪荷载设计方法,通过加强施工监管,预防、降低冰雪灾害工程事故的发生,为建筑结构雪荷载设计与施工提供指导。
For improving the disaster-prevention capacity, this paper puts forward the adoption of snow pressure based on the analysis of engineering accident in the 2008 snow disaster in southern China, analyzes the mechanism of roof height differences, roof pitch, roof shapes and the local wind speed, puts forward the design methods, and emphasizes the construction management to prevent and decrease engineering accidents caused by snow disasters.
