【摘要】 提出了一种利用钢梁腹板锯齿边作为抗剪连接件的钢-混凝土组合梁,从而省去了栓钉连接件.为了研究这种组合梁的可行性及其在静载作用下的力学性能,完成了跨中两点对称集中加载的组合梁试验,分析了其抗弯承载力、应力分布及纵向抗剪等性能.研究表明这种新型组合梁具有较好的刚度、承载能力和延性,破坏形式为弯剪型,连接件抗剪性能好,具有较好的经济效益和应用前景.更多还原

【Abstract】 A type of composite steel -concrete beam with web saw tooth edge as shear connector is put forward and the stub is canceled.The experiment of this composite steel - concrete beam under concentrate loads is completed in order to study feasibility of this composite steel - concrete beam and its mechanical behaviors.The bending capacity,stress distribution and longitudinal shear are analyzed.The experimental results show the new composite steel -concrete beam has good rigidity,bending capacity and ductility,the destructive is bending and shear mode,and the performance of shear connector is good.So this new type of composite steel - beam has good economy benefit and expansive applied foreground.更多还原
