The existing push-out test results showed that the ultimate shear capacities and ultimate slips of tie-bars and studs under cyclic loading were significantly lower than those under monotonic loading, which could significantly affect the seismic performance of steel–plate concrete composite (SC) structures. The flexural behavior of two SC beams subjected to cyclic loading was investigated. Specimen SCB1 using tie-bars was partial shear connection, and specimen SCB2 using tie-bars and studs was full shear connection. The failure modes, hysteresis curves, skeleton curves, equivalent lateral stiffness, energy dissipation, interfacial slip distribution, interfacial shear distributions, and strain in steel plates were researched. The experimental results show that two SC specimens were brittle failure, which primarily resulted from premature shear fracture of shear connectors at the interfaces between steel plate and concrete. Finally, two existing codes for SC structures were used to analyze the bending moment and shear of SC beams as well as interfacial shear of tie-bars and studs. This indicates that due to the difference of shear connection ratio between two specimens, the interfacial shear distributions of two SC beams were significantly different.

现有的推出试验结果表明，循环荷载作用下拉杆和螺柱的极限抗剪承载力和极限滑移明显低于单调荷载作用下的抗剪承载力和极限滑移，这可能会显着影响钢板混凝土复合材料（SC）的抗震性能。结构。研究了两个承受循环荷载的超临界梁的弯曲行为。使用拉杆的试件SCB1是部分剪切连接，使用拉杆和螺柱的试件SCB2是完全剪切连接。研究了钢板的破坏模式，滞后曲线，骨架曲线，等效横向刚度，能量耗散，界面滑移分布，界面剪切分布和应变。实验结果表明，两个SC试样均为脆性破坏，这主要是由于钢板和混凝土界面处的剪切连接器过早发生剪切断裂。最后，使用两个现有的SC结构规范来分析SC梁的弯矩和剪切力以及拉杆和螺柱的界面剪切力。这表明，由于两个试件之间的剪切连接比不同，两个SC梁的界面剪切分布存在显着差异。
