Influence of Low Yield Point Reinforcement and High Toughness Concrete on Seismic Performance of the Frame

Currently, ordinary concrete and steel bars are mostly used in frames, but there is no systematic research on the impact of high toughness low yield point seismic performance frames. The low-cycle repeated load test three 1/3 ratio two-story two-span cast-in-situ frame specimens carried out. resilience model hysteresis characteristics, displacement ductility, energy dissipation capacity studied analyzed by experiment. In addition, a comparative analysis made between with reinforcement. restoring force reinforced (RC) reinforcement given. results show that has better ductility lateral stiffness than frame. will be improved using concrete. deformation ability members
