Shear Lag Factors for Longitudinally Welded Tension Members [N28]

Based on an AISC Engineering Journal paper from the First Quarter of 2012, recommendations for a generalized design procedure for welded connections of plate, angle, channel and tee tension members regardless of the length of the weld or if the length of the longitudinal welds are unequal information will be presented. A summary of the treatment of various current building codes/specifications (AISC and CSA) on this topic is presented along with the results of several published experimental research projects that evaluated the behavior of these types of connections. Two analytical models are presented, and recommendations for changes to the current AISC Specification are made, followed by an example problem illustrating the practical application of the recommendations.
