The primary objective of the study was to assess the suitability of using Lshaped RC columns in regions of low-to-moderate seismic risk. The variables of interest included the axial load, loading direction and aspect ratio. The specimen performances were analyzed and discussed in terms of crack patterns, hysteretic response. Results highlighted that the L-shaped columns possess good seismic resistance; Failure mechanism of L-shaped columns was mainly governed by vertical splitting cracks; Shear strength of L-shaped columns were not significantly affected by the level of applied axial force and the direction of horizontal force while initial stiffness was considerably affected by aspect ratio. Further analysis showed that ignoring the contribution of flanges, the shear equation (special provisions for walls) in ACI 318-11 yields good estimations of shear strength for the cases of L-shaped columns.
