| 摘 要： | 为验证新型装配式圆钢管柱-钢梁节点的破坏模式及抗震性能，进行了3个十字形节点的低周反复循环加载试验。研究了不同试件节点的破坏模式、滞回性能、延性及耗能性能等。试验结果表明:试件的位移延性系数为3.38~3.44，能量耗散系数为1.72~2.25，节点具有良好的滞回性能、延性及耗能能力，满足现行规范设计要求。建议在采用新型装配式节点时，梁柱连接处可同时采用加强型连接或骨式连接，以获得良好的抗震性能。

| Abstract: | In order to verify the failure modes and the seismic behavior of a new type of prefabricated joint composed of steel tubular column and steel beam, three cross shaper specimens are tested under cyclic loading. The failure modes, hysteretic behavior, ductility and energy dissipation properties are studied. Experimental results of the three specimens showed that the story drift ductility ratios μ≈3.38~3.44 and energy dissipation ratios E≈1.72~2.25, the joints have good hysteretic behavior, ductility and energy dissipation capacity, which satisfies the requirements of the current structural codes. It is suggested that when the new prefabricated type joint is adopted in practical engineering, the strengthened beam-to-cloumn connection or dog-bone beam-to-cloumn connection is suggested to be used simultaneously in the beam-column joint, which will have a positive seismic performance. |
