摘要：
A half scale single-bay and two-story frame model was made, which was composed of reinforced concrete (RC) beams and T-shaped steel reinforced concrete (SRC) columns. The pseudo-dynamic test method was used to investigate seismic behaviors of the frame such as seismic responses and energy dissipation, and El centro earthquake waves with different peak acceleration were applied on the frame in the test. The experimental results indicate that structural damage due to earthquake is mainly located at the beam ends, and dynamic coefficients at the floors lie between 1.08 and 2.25. Additionalloy, the maximum inter-story drift angles of the frame meet the limitation requirement specified by Chinese codes. The lateral stiffness of the frame reduces by 6% after it is subjected to the earthquake wave with peak acceleration 1 000 cm/s2. Frames with SRC special-shaped columns possess good seismic performance and they are feasible to be applied in high intensity earthquake zone. ©, 2015, Central South University of Technology.
