- The drift capacity of concrete columns with very low transverse reinforcement has seldom been studied. Very low reinforcement is prohibited by design standards, but such columns are prevalent in many old buildings, particularly in developing countries. The seismic performance and drift capacity of lightly reinforced concrete columns were investigated in this paper, with emphasis on identification of gravity collapse load. To this end, a unique test setup with a vertical hydraulic jack constrained to move horizontally on guided rollers was emolyed, thereby maintaining the verticality of the axial load. The adverse effect of longitudinal bar buckling on the shear capacity of columns is clearly revealed from the tests.
