摘要

摘要: 组合楼盖中钢与混凝土之间的剪力传递是通过设置在钢与混凝土之间的剪力连接件实现的。开孔板式抗剪件具有抗剪承载力大、抗疲劳性能好、施工简单的特点。根据剪力传递的方式设计出适用于建筑领域的开孔板式抗剪件。采用静力推出试验方法,通过11个模型试验,研究分析出该种抗剪板的破坏形态以及抗剪钢板厚度、高度、开孔直径、孔内钢筋直径、穿孔钢筋的有无等因素对抗剪板抗剪承载能力和抗滑移特征的影响。结果表明:该种抗剪件具有良好的力学性和经济性,特别是在开孔中穿钢筋时,可大幅度提高试件的抗剪承载力和延性性能。

Abstract: Structure behavior of composite member depends largely on performance of shear connector.In this paper, shear connector formed by rectangular steel with two holes,applicable to composite beam in building structure,was presented.Failure modes and influences of the geometric dimensions on performance of the connector were studied and analyzed through eleven static push-out model tests,the geometric dimensions including height and thickness of the plate,diameters of the holes,and diameter of reinforcement bars through the holes and so on.It is shown that the proposed connector has good mechanical properties and is more economic,especially the ones with reinforced bars through the open holes have larger strength and better ductility．
