［摘要］针对门式刚架风荷载体型系数按跨高比分别采用不同标准取值的混用法提出不同观点，指出其缺少必要的理论依据和试验验证，不符合现行荷载规范体型系数的原则及体型系数所具有的属性要求，也与先进国家风荷载计算的基本理念相左。体型系数取值与门式刚架跨高比无关。

Abstract:There are different points of view about mixed method for determining different standard values of the shape factors of wind load of  steel portal frames according to the span-to-height ratio respectively. It points out that it lacks necessary theory basis and test verification, and it does not meet the property requirements of shape factor and shape factor principle of existing load code, and it is also opposite to the basic concepts of the wind load calculation of advanced countries. The value of shape factor is independent of the span-to-height ratio of steel portal frame.

Keywords:steel portal frame; shape factor of wind load; span-to-height ratio
