摘　　要：通过对循环荷载作用下的狗骨式刚性连接节点的试验研究，分析了狗骨式刚性连接的滞回性能。试验结果表明：狗骨式刚性连接具有良好的延性和耗能能力，节点的转角都超过了0.03rad；焊缝强度和梁翼缘的削弱程度是影响节点滞回性能和极限承载力的决定因素。最后，根据试验结果提出了此类连接的设计和施工建议。The hysteretic behavior of dog-bone style beam-column connections under cyclic loading is presented in this paper.Results of the experiment show that the dog-bone style connections have better behavior of ductility and energy dissipation, and the rotations of all connections exceed 0.03 radians. The strength of weld seams and the weaken degree of beam flanges are those of the most important factors, which have crucial influence on the cyclic behavior of connections. In the end, suggestions on design and fabrication about this type connections based on the experiment results are presented.
