“…Nie et al [10] carried out seismic research on the end-plate edge connection of a steel beam to the weak axis of an H-shaped column with a U-shaped connector and proposed the end-plate's thickness and the stiffener's structural value. Lu and Wang [11][12][13] proposed the box-shaped panel zone end-plate connection for the weak-axis column, and the seismic performance of the joints with stiffener at the beam end was analyzed. The results showed that the stiffness and bearing capacity of the joint could be improved effectively by setting a stiffener in the joint.…”

The seismic behavior of the end-plate connections between a steel beam and the weak axis of the H-shaped steel column using a U-shaped connector was investigated using numerical analysis. Finite element (FE) models were established using ABAQUS 6.14 software, and the applicability of the modeling approach was verified by comparing the numerical results with the relevant experimental results. This parametric study of the joint was carried out to analyze the effects of the thickness of the U-shaped connectors, the thickness of the end-plates, the axial compression ratio of the columns, and the linear stiffness ratio of the beam to the column. The results show that the U-shaped connector set in the weak axis of the H-shaped column can form a box-shaped panel zone with the column flange and web. The volume of the panel zone and its resistance to shear deformation are increased through this connection. Finally, the recommended reasonable ranges for the thickness of the U-shaped connector, the thickness of the end-plates, the axial compression ratio of the columns, and the linear stiffness ratio of the beam to the column are proposed in this paper.
