建筑围护结构风荷载的计算与取值

Calculation and Selection of wind load for enclosure structures of buildings

风荷载为建筑中受力结构和围护结构的主要可变荷载,现行建筑结构荷载规范分别列出了受力结构和围护结构风荷载wk的计算公式,但依据不同规范计算所得结果差别较大.这里通过采用不同规范,对风荷载值进行计算分析比较,提出建筑设计中wk计算公式的选用及相关建议,供设计人员参考.

Wind load is the main variable load in bearing structures and enclosure structures. The current load codes for the design of building structures respectively list the calculation formula of Wk for bearing structures and enclosure structures, but there is a great difference between calculation results according to different specifications. In this paper, the wind loads for enclosure structures based on three norms are analyzed and discussed, and some related suggestions are put forward.
