Cyclic Behavior of Spatial Beam-to-side Column Joint with T-stub
Abstract
In order to study the cyclic behavior of spatial semi-rigid beam-to-side column joint with T-stub. The side column connections of steel frame as the research object and there is one spatial T-stub connection specimen and one plane T-stub connection specimen. Spatial cyclic load of quasi-static tests and finite element analysis are carried out, which load is 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 are analyzed. 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.
