摘要：The prediction of the behaviour of spatial beam to column joints relies on experimental and numerical tests that provide accurate information for the mechanical characterization of the joints. This study focused on the seismic behaviour of semi-rigid beam to side column space joints which connected with T-stubs. Beam to side column joints in the steel frame structures were considered as research objects to perform a spatial pseudo-static test on two joint models of a spatial subdivision, with end column as the load mode. The models of spatial beam to side column connection with T-stub implemented in the ABAQUS which takes into account the non-linear geometrical and material behaviour, non-linear contact and slip. Based on the experimental and numerical results, analyses were conducted on the deformation characteristics, plasticity status and failure modes of the joints, as well as the strengths, rotational stiffness, hysteretic characteristics, ductility coefficients, and energy dissipation properties of different joints. The results indicate that under the action of a spatial load, the relevant mechanical properties of the spatial semi-rigid joints were affected to varying degrees.
