Cover Story (view full-size image): A half-scale hollow-core fiber-reinforced polymer–concrete–steel (HC–FCS) column, was subjected to cyclic torsional loading. The column consisted of an outer fiber-reinforced polymer (FRP) tube and an inner steel tube, with a concrete shell sandwiched between the two. The FRP tube was ended at the surface of the footing, providing confinement to the concrete shell, while the steel tube was fully embedded into the footing. In comparison with conventional reinforced concrete (RC) columns, the HC–FCS column maintained the torsion strength until a high twist angle, whereas the RC column did not. View this paper
