This study explores the seismic behavior of embedded steel plate in the coupling beam through five sets of specimens. The experimental results show that for coupling beam with a vertical main reinforcement in straight-through configuration, when the lateral displacement increases, the concrete may be crushed due to the decrease of the shear capacity and shear damage occurs. The scheme of using lateral stirrups can effectively provide a composite mechanism between steel plates and concrete. With an embedded steel plate and a good composite of the steel plate and concrete, the shear capacity of the beam can be improved and the failure mode of the test specimens can be transformed into flexural failure. The design of the end bearing plate and the stiffening plate may cause the concrete around the end to be crushed. This shows that the anchoring mechanism of the steel plate can be further improved. |
