摘要: 对12个足尺钢管混凝土柱-钢梁外加强环空间节点进行了静力试验。基于挠度法,对节点刚度进行了测试。根据测试结果,分析了影响节点刚性的各种因素。最后指出,外加强环式节点可以当作刚性节点使用,但必须满足一定的条件,即外加强环必须具有足够的刚度。另外这种节点还具有明显的空间特性。

Abstract: An experimental research on 12 full size specimens of CFT- steel beam space joint with outer concentric annularstiffer. Tested the joint stiffness based on0 deflection method0 , and analyzed the factors that affect joint stiffness according to the test results. In the end, the paper indicated that the joint with outer concentric annular- stiffer can be used as rigid joint, but this must suffice to a certain condition, i. e. the outer concentric annular- stiffer must have enough stiffness. In addition, this kind joint has obvious space characteristic.
