摘　　要： 针对钢结构设计的难点——特殊的不规则布置梁柱连接节点的设计进行了研究。首先介绍了双层不规则布置梁加强环式梁柱节点的足尺模型试验,考察了该类型节点的受力性能和破坏机理。然后对试验模型进行了相应的有限元数值模拟,验证了该有限元模型和分析方法的合理性。在此模型基础上,利用有限元程序进行了参数分析。最后综合试验和有限元分析结果,提出了双层不规则布置梁加强环式梁柱节点承载力和刚度的计算方法,可供实际工程设计参考。 The beam-column joint strengthened by plate rings is the most mature and widely used steel joint. In the paper the experiments on the full-scale specimens of typical joints strengthened by plate rings with irregular arranged double level beams were conducted to investigate the mechanical performances and failure mechanisms. The specimens were also numerically simulated by the finite element analysis（FEA） program, and good agreement between the simulated results and the test data demonstrated the validity of the established FEA model. The parametric analysis was also carried out using the FEA model. Finally, the calculation formulas for the load capacity and the stiffness of the beam-column joint strengthened by plate rings with irregularly arranged double level beams were proposed for reference in the practical designs.
