Abstract: In this paper the shear lag effect in the flange of Tee-beams is calculated by the bar simulation method, and an indistinct concept which preexists in the calculation of the moment of inertia of cross sections according to the effective width of flange is clarified, thus,the direet stress values in flauge obtained by the current simplified compution agree well with these practical maximum.

摘要： 本文用比拟杆法计算T形梁翼缘的剪力滞效应,并对已往按翼缘有效宽度计算截面抗弯惯矩中存在的一种模糊概念进行了澄清,从而使现行的简化计算方法所得的翼缘应力值与实际的最大应力值得到了符合。
