要旨 Eight 250x250x1000mm reinforced concrete columns confined in square steel tubes were fabricated and tasted under reversed cyclic shear-bending type of loading in the presence of specified axial load levels. The main parameters were the wall-thickness ratio of the tubes, which varied from 28 to 117, and the axial load levels of 33 and 67% of the concrete's gross sectional capacity. The wall-thickness of the tubes did not show significant effect on the load-deflection curves of the columns at low axial load levels, but the effect was remarkable at high axial load levels. Stiffeners inside critical regions of tubes brought about large ductility.
