摘　　要：以现存偏心钢筋混凝土梁柱节点为研究对象,通过试验方法测试其抗剪承载力,并与规范的计算结果进行了比较。结果表明,偏心梁柱节点核芯区的截面抗震受剪承载力低于规范设计值,应在现行规范的基础上建立更为合理的方法,来考虑由于梁柱轴线不重合引起的扭矩作用对梁柱节点抗震性能的影响。The research subject is an eccentric reinforced concrete beam-column joint. Experiment study under low cycle loading is presented on the joint,the shear capacity of which is compared with the specification-based approach. The results indicate that the shear bearing capacity of the eccentric beam-column joint is lower than the value of current specifications,which may cause the shear failure of the beam-column joints under seismic action. Based on the current codes,a more reasonable method should be established to consider the influence of the torque on the seismic performance of the beam-column joints,which is caused by the misalignment of the beam and column axis.
