The Effect of Splicing Area Parameters on Mechanical Behavior of Beam-Column Connection with Cantilever Beam Splicing

Abstract

This paper deals with the effect of splicing area design parameters on the mechanical behavior of beam-column connection with cantilever beam splicing. A series of models are designed based on the change of parameters. The mechanical behavior of beam-column connection with cantilever beam splicing is systematically studied by using the finite element analysis. The analysis results show that the number and arrangement of web bolt will have a great influence on mechanical behavior of the splicing joint when the number of flange bolt is designed by the precise design method; the number and arrangement of web bolt will have a less influence when the number of flange bolt is designed by the equal strength design method; Splicing area design parameters have little effect on the ultimate load and the initial rotational stiffness of the splicing joint; the number and arrangement of bolt is sensitive parameter for yield load of the splicing joint and the rotational stiffness in the the splicing area.
