摘要
对我国建筑结构荷载规范(GB50009-2001)与美国荷载规范(ASCE7-05)中开敞式高耸钢结构风荷载计算方法进行比较,分析了两者取值的异同性.以某开敞式中心支撑钢框架为例,发现由美国规范得到的结构基底剪力约为我国规范计算的1.2～1.3倍,采用美国荷载规范ASCE7-05取值更偏于安全.
In this paper,horizontal wind load calculation methods about open high-rise steel structures between Chinese and American Codes are compared.Taking an open concentrically braced steel frame as an example,the author find the base shear calculated on the basis of ASCE7-05 is about 1.2-1.3 times higher than calculated in accordance with Chinese code.Structures will be much safer if wind load is calculated according to ASCE7-05.
