【摘要】 近年来钢梁-钢筋混凝土柱框架结构(RCS)在美日等国获得广泛研究和应用,为了解这种新型结构节点的受力机理,建立了节点受力模型,详细分析了RCS组合结构节点抵抗剪力的三种传力机构的受力机理与传力方式。指出节点承载力主要是由钢梁腹板及混凝土斜压杆所提供,根据节点受力模型建立承载力公式是可行的,最后根据国外的研究资料,分析比较了业已提出的RCS节点抗剪计算公式。更多还原

【Abstract】 In recent years,a new type of composite structure consisting of steel beam and reinforced concrete column(RCS) has been researched and used greatly,to understand the shear mechanism of the joint,the joint model of RCS composite structure is established,the shear mechanism and force transferring system of the three mechanisms which resist the shear force are analyzed in detail.The strength of the joints is given by contributions from the steel web panel and concrete diagonal struts,the joint model is capable of predicting the shear force.At last some design equations of the RCS beam-column connection are introduced and compared according to the existing research data.更多还原
