Abstract

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.
