【 摘 要 】

The prediction of the behaviour of Spatial joint and plane joint relied on experimental and numerical tests that provide accurate information for the characterization of the beam to Column connection with T-stub. The corner column connections of steel frame as the research object and there are one spatial T-stub connection specimen and one plane T-stub connection specimen. Spatial cyclic load of quasi-static tests and finite element analysis were carried out, of which load was applied to the column. According to the results of quasi-static tests and finite element calculations, difference of joints' rotational stiffness, hysteretic property, ductility coefficient and energy dissipation characteristics were analysed. It is verified that the mechanical characteristics of spatial semi-rigid joint under spatial load are different from plane semi-rigid joint under plane load.
