- Title
Analytical approach for shear lag in welded tension members.

- Abstract
The authors propose an analytical approach for calculating the reduction in strength of steel tension members due to shear lag effects. The approach is based on an assumed distribution of forces along inclined lines in the member ends, somewhat similar to the Whitmore concept used with gusset plates for bracing members. The method is demonstrated for a basic weld in shear at elastic, plastic, and ultimate stress levels. The method is then compared with the recommendations contained in standard CAN/CSA-S16-01 for elements connected by a single longitudinal weld and for elements connected by longitudinal welds along two parallel edges. The predicted strength of tension members with welded connections is compared with results from several laboratory tests. The proposed method could be used for calculating the reduction in strength due to shear lag effects of tension members with different sections.
