The bearing flaps and stiffening plates at the end of the steel plate will destroy the anchoring zone, causing the strength of the steel-containing connecting beam to decay rapidly. In this study, five high-strength reinforced concrete connecting beams were designed and built-in steel plate specimens, with the addition of shearing nails, anchor length and treatment, and the addition of lateral ribs and steel plates to the main design variables. The experimental results show that the built-in steel plate and the lateral ribs and the additional shear nails can increase the shear capacity of the beam, and the failure mode changes from shear failure to flexural failure. The lateral reinforcement of the steel plate is added to the steel plate. Shear studs can improve the composite between concrete and steel plate and transmit shear force. The anchor length of the end of the steel plate is sufficient and the configuration of shear pins and openings can be used to effectively improve the damage of the anchoring zone. The standard test piece configuration steel plate can improve the maximum lateral force strength, displacement capacity, cumulative energy dissipation and initial stiffness of the test piece when the steel plate is anchored and the beam body is well compounded.
