摘　　要：通过低周反复荷载试验研究了方钢管混凝土结构的抗震性能。结果表明,与钢梁相交的方钢管混凝土节点结构具有承载能力大、滞回特性稳定、延性大和吸收能量多等优点。试验结果与根据现有规范计算得到的结果具有较好的一致性。The structural behavior of connections with steel diaphragm between CFRT （concrete-filled rectangular tubular） column and steel beam is studied in this paper through sub-assemblage loading tests. It is indicated that the test structures with steel beams rigidly framed into CFRT column have adequate bearing capacity, stable hysteresis characteristics, good ductility and energy- absorbing capacities. Excellent agreement is exhibited between experiment results and those based on present codes.
