Abstract: The seismic performance of reinforced concrete frame structure with embedded steel plates is researched that adopt the 2-layer single-span 1/3-scale model. And we design a reinforced concrete frame with embedded steel plates and compared with a reinforced concrete frame. Using low reversed cyclic loading test, the research on reinforced concrete fram with embedded steel plates’s specimen failure mechanism, hysteretic performance, stiffness degradation law, ductility and energy dissipation capacity, and compared with reinforced concrete frame. Test results show that the damage mechanism of reinforced concrete frame with embedded steel plates is more reasonable. The deformation ability, the lateral stiffness and bearing capacity are obviously higher. Before the structure yield, there is no obvious crack in the beam and column. The second layer of the steel plate is fully developed than the first layer and the main stress is in the diagonal direction. The results of ABAQUS finite element analysis are consistent with the experimental results. 

Keywords:embedded steel plate; low reversed cyclic loading test; seismic performance; hysteretic performance; stiffness degradation law; ductility; energy dissipation capacity
