摘　　要：通过2个不规则布置梁双层加强环式梁柱节点的足尺模型试验,研究该类型节点的受力性能和破坏机理.实验结果表明,加强环板能有效地将梁翼缘的应力传递至钢管壁,加强环板与钢管壁能共同工作,该相互作用对柱钢管壁有一定的影响;合理的设计可以保证该类型节点具有良好的工作性能.In this paper, two full-scale typical joint specimens strengthened by plate rings with irregularly arranged double levels beams are conducted to learn the mechanical behavior and collapse mechanism. The tests imply that the stresses in the beam flanges can be effectively transferred by the strengthening plate to the steel tube,and the inbetween co-activity will be somewhat affected when stressed simultaneously. Good working performances of this type of joint can be guaranteed with rational designs.
