这个取决于你肘板的尺寸有多大厚度有多厚。通常情况下,当肘板厚度小于15倍的自由边长时需要做面板或者加强,这里肘板取毫米,自由边尺寸取米。所加面板的截面积,不小于10倍的自由边长,这里,面积取平方厘米,自由边长取米。在规范里找到一句话,供你参考。
The net thickness of brackets is to be not less than that of ordinary stiffeners. Brackets with net thickness, in mm, less than 15Lp, where Lp is the length, in m, of the free edge of the end bracket, are to be flanged orr stiffened by a welded face plate. The net sectional area, in cm2, of the flanged edge or face plate is to be at least equal to 10Lp. |
