Abstract: This paper presents a numerical study of the shear lag effects on high strength steel (HSS) bolted and welded single anglesby the finite element method. The finite element models used in the study were calibrated by the test results of normal strength steel angles subjected to tension. In total, fourteen HSS angles were simulated and typical HSS material properties used in the analysis were obtained from the literature. The parameters examined in the study includedthe connection length and the connection eccentricity. It is observed that the tensile capacity and final elongation of the HSS angles are considerably lower than those of the corresponding normal steel angles. The widely used 1−푥 /퐿rule in general overestimated the capacities of the HSS bolted single angles but provided conservative estimates of the capacities of the welded ones examined in this study.
