［摘要］針對門式剛架風荷載體型系數(shù)按跨高比分別采用不同標準取值的混用法提出不同觀點，指出其缺少必要的理論依據(jù)和試驗驗證，不符合現(xiàn)行荷載規(guī)范體型系數(shù)的原則及體型系數(shù)所具有的屬性要求，也與先進國家風荷載計算的基本理念相左。體型系數(shù)取值與門式剛架跨高比無關(guān)。

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
