摘要:
部分连接钢构件由于存在剪切滞后现象，截面强度不能充分发挥，在设计中应予以足够重视.针对侧面角焊缝连接轴心受力板件，基于应力扩散概念，建立弹性和弹塑性剪切滞后模型，并借助有限元分析软件以及应力扩散角的计算可较为准确地获得危险截面上的正应力分布.通过与国外相关标准、试验数据进行对比分析，结合危险截面的塑性区范围，提出了剪切滞后系数的实用计算公式，以便工程设计应用.
Abstract:
The section strength of steel member by partly connecting could not be fully realized due to the presence of shear lag, which should be given more attention Based on the concept of stress diffusion, the elastic and elasticplastic models for shear lag of axial forced plate connected by side fillet weld are established With the help of the finite element analysis software, the normal stress distribution could be obtained accurately through the calculation of stress diffusion angle Compared with foreign standards and test data, and considered the plastic range at critical section, the practical formula for shear lag coefficient is obtained for design purpose, which could be used easily and conveniently.
