摘　　要：通过一片带有双排开孔钢板连接件的钢-混凝土组合梁的两点对称加载试验,对交界面处混凝土板与钢梁的相对滑移、交界面处应变差、跨中截面的应变发展变化以及横向贯通钢筋的荷载-应变关系等进行了分析,进而研究了开孔钢板连接件的受力和抗滑移性能。结果表明,该连接件受力性能较好,抗滑移性能明显优于栓钉连接件。By a loaded experiment on the two symmetrical joints in the steel-concrete composite beam with twin perfobond shear connectors,the paper analyzed the relative slip at the cross-section between the concrete plate and steel,the bad strain at the cross-section,the strain development at the middle section and the relation be-tween the load and strain of the throughout steels,and then studied the mechanic property and anti-slippery of perfobond shear connectors.The results indicated that the connector has good mechanic property,and the anti-slippery of the connector is better than that of the stud.
