摘要

当拉力荷载传递给受拉构件的部分而不是全部截面单元时,拉力在受拉构件的截面面积上不是均匀分布的。受拉构件中的不均匀应力分布通常被称为面外剪切滞后效应。然而,现行的美国钢结构协会(AISC)规范在确定除板和空心结构截面(HSS)以外的受拉构件的剪切滞后因素时,并没有解决不等长纵向焊缝和面内剪切滞后效应。本文的目的是提出一种考虑不等长纵向焊接角面内面外剪切滞后效应的剪切滞后因子的计算方法。利用三维实体单元的有限元方法和考虑复合材料和几何非线性的非线性静力分析,验证了所提出程序的准确性。

Shear Lag Factors for Tension Angles with Unequal-Length Longitudinal Welds
: When a tension load is transmitted to some, but not all of the cross-sectional elements of a tension member, the tensile force is not uniformly distributed over the cross-sectional area of the tension member. The non-uniform stress distribution in the tension member is commonly referred to as the out-of-plane shear lag effect. The unequal-length longitudinal welds and the in-plane shear lag effect, however, are not addressed by the current American Institute of Steel Construction (AISC) Specification for the determination of the shear lag factors for tension members other than plates and Hollow Structural Sections (HSS). The purpose of this work is to propose a procedure for the computation of shear lag factors accounting for combined in-plane and out-of-plane shear lag effects on unequal-length longitudinal welded angles. The finite element method using three-dimensional solid elements and nonlinear static analyses accounting for combined material and geometric nonlinearities are conducted in this work to verify the accuracy of the proposed procedure.
