in order to study the mechanical properties of steel-concrete composite beams with asymmetric friction connections and considering the structural factors, three simple steel-concrete composite beams with friction connections were fabricated, and the uniaxial low cycle cyclic loading sine wave tests were carried out on the steel-concrete composite beams with friction connections. The test results show that the composite beam can get stable two-stage hysteretic curve in structure 1 and structure 3, and has reliable hysteretic energy dissipation capacity. The hysteretic curve of structure 1 is more full and stable, and the strength increases first and then decreases with the loading.

为研究非对称摩擦连接钢-混凝土组合梁的力学性能，并考虑结构因素，制作了3个简单的摩擦连接钢-混凝土组合梁，并对其进行了单轴低周循环加载正弦波试验。采用摩擦连接的钢-混凝土组合梁。试验结果表明，该组合梁在结构1和结构3中均能得到稳定的两级滞回曲线，具有可靠的滞回耗能能力。结构1的滞回曲线更加饱满和稳定，强度随荷载先增大后减小。
