The macro-synthetic fiber is widely used to prevent the cracking at concrete members. By the way of experiment that macro-synthetic fiber-reinforced concrete ductile columns comparing with the usual fiber-reinforced columns under the action of low-frequency cyclic loading, seismic performance of the columns in different form of bars were obtained. Meanwhile, the damage pattern, hysteresis curve, ductile coefficient and equivalent viscous damping coefficient of the columns could be also obtained. The results show that the macro-synthetic fiber-reinforced concrete ductile column has the better ductility and the higher post-crack energy absorption ability.
