摘　　要：变电站塔架是高耸建筑物重要的结构形式,风荷载是其主要设计荷载。本文通过对比中、美、日、澳、欧等国现行荷载规范中变电站格构式塔架风荷载体型系数相关公式及参数设定,更好理解我国规范体型系数取值与各国规范的差异。结果表明:各国规范体型系数变化与挡风系数相关,可作出两者关系曲线;中国《建筑结构荷载规范》(GB-50009-2012)体型系数取值总体小于其他荷载规范。Substation tower is an important structural form of high-rise buildings, and wind load is main design load.This paper compares the formulas and parameter settings of the shape coefficient of the lattice tower of substation in the current load codes in China, the United States, Japan, Australia, Europe and other countries to better understand the difference between the value of the shape coefficient of China’s code and the codes of other countries.The results show that the variation of body type coefficient in different countries is related to the windscreen coefficient, and the relationship curve can be made;The value of shape coefficient of China’s "Building Structure Load Code"(GB-50009-2012) is smaller than other load specifications.
