摘要
国内外多次地震灾害表明,钢筋混凝土框架结构的倒塌,多数是由梁柱节点破坏引起。然而目前,我国规范(GB50011-2010)中对节点抗剪承载力的计算仍采用的是半经验半理论公式,缺乏理论依据。本文通过各国钢筋混凝土梁柱节点试验研究、理论研究及数值模拟研究,归纳了节点抗震性能研究发展状况,并指出了目前研究存在的主要问题和研究方向。
A variety of earthquake disasters have crete frame structure is primarily caused by the failure indicated that the collapse of the reinforced con- of the beam-column joint. However, the calculation of the shear bearing capacity of the joint has been based on the semi-analytic method in the current standard （GB50011 -2010） at present, which is lack of theoretical basis. Based on the experimental, theoretical and numerical simulation researches, the seismic performance of RC beam-column joints are summarized and the main problems of current research and the research direction are pointed out.
