Numerical Investigation of Shear Lag on Channel Tension Members

Shear lag is one of the main phenomenon governing the strength of steel tension members connected eccentrically. This paper presents the effect of shear lag on welded channel sections analysed using finite element method. The finite element model considered in the study consists of channel sections with either the web or flange connected to a gusset plate by means of welded connection at both ends of the member. The loading and boundary conditions are applied through the gusset plates. The major parameters incorporated in the analysis are as follows: the grade of steel, length of the weld, thickness of the weld, area of contact, orientation of the section, and out-of-plane eccentricity. The orientation of the section with flange connected to the gusset plate has a higher reduction in the capacity while compared to web connected to the gusset plate. Also, the increase in length of weld improves the shear lag factor of channels connected to gusset plate through web, whereas the length of weld has negligible influence on channels with flange connected to gusset plate. The shear lag factor determined using finite element analysis is comparable with the design recommendations for shear lag provided by American and Canadian standards.
