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。
An experimental research on 12 full size specimens of CFT-steel beam space joint with outer concentric annularstiffer. Tested the joint stiffness based on ＂deflection method＂, 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.
