%X Taking a reactive power concrete (RPC) box pier as the object of study, 3 specimens with reasonable cross-section size and structure conformation were firstly designed. The effect of the direction angle of horizontal loading on the seismic performance of RPC box pier was experimentally studied through applying constant axial force and horizontal cyclic load. The ductility, hysteresis curve, skeleton curve, load degradation curve and stiffness degradation curve of specimen were studied, and the displacement ductility factor and energy loss factor of specimens were obtained. Non-linear numerical analysis program describing the complete process of specimen under one-way loading was compiled and verified by experimental results. Numerical and experimental results show that RPC box pier presents good seismic performance, and the direction angle of horizontal loading is a key factor in seismic performance of box pier, and the component subjected to oblique force presents weaker seismic performance than that of component subjected to axial force.
