Concrete filled steel tube (CFT) members have been applied to the columns of rigid frame structures. However, the failure mode, the bending capacity and deformation performance of CFT members with small shear-span ratio are not clear because there have been few studies on them. In this study, cyclic loading tests were conducted on short-column CFT members with constant vertical loads. As a result, it was confirmed that they show a flexural failure mode, but the existing design method overestimates their bending capacity. Therefore, a new evaluation method was proposed for their bending capacity and deformation performance.
