In this paper, the seismic behavior of Steel Reinforced Ultra-High Strength Concrete (SRUHSC) frames is experimentally studied under cyclic loading. Three one story-one span frames are carried out, and the main parameter is axial compression ratio. The major purpose is to investigate the seismic behavior of frames with the increasing of axial compression ratio, meanwhile, analysis the hysteresis curve, skeleton curve, stiffness degradation, energy dissipation and residual displacements. The test results reveal that the seismic response of the frame is closely related to the failure process and failure mode of the columns, which indicates that as the axial compression ratio increases, the failure process of the entire structure and the weakening of the beam end are accelerated. Meanwhile, a change of the failure mode is also observed, accompanied by corresponding changes in the strength, stiffness and energy dissipation capacity, and the seismic behavior of frame structure decreases.
