摘　　要：通过5个框架节点的试验,研究节点的破坏形态、延性、滞回特性及抗剪切性能。试验结果表明,所提出的钢管混凝土核心柱预应力梁框架节点设计方法是可靠的,该节点形式具有很好的延性和能量耗散能力,由于柱为钢管混凝土核心柱,大大提高了节点核心区的抗剪承载力。The failure mode, ductility, hysteretie characteristics and shear property of the joints are studied by the tests for five frame joints of concrete-filled steel tubular core columns and prestressed concrete beams. The experimental results indicate that the construction methods are feasible and safe, and such joints have good ductility and good energy dissipation. With the concrete-filled steel tube core columns, the shear bearing capacity of core area of joints can be raised greatly.
