Columns in lateral-force-resisting frames are designed with these deformations in mind, but gravity columns often are not. When gravity columns are continuous, moments develop when interstory drifts occur. Using nonlinear dynamic analysis software, moments due to lateral deformation from seismic forces were obtained for lateral-force-resisting columns within 3- and 9-story buckling-restrained-brace frames (BRBFs). Moments in gravity columns were then determined. Gravity columns were evaluated with interaction equations to determine whether load demands exceeded column capacity. For most gravity columns, column capacity was exceeded. Recommendations for improved gravity column design are given.
