Abstract

Abstract

The self-piercing riveting (SPR) connection has the outstanding advantages of good mechanical properties and high connection efficiency, and has a good application prospect in cold-formed steel (CFS) structures. Adopting 8 simplified methods including equivalent area coupling, constraint element and connection element, to establish the simplified finite element model of cold-formed steel self-piercing riveting (CFSSPR) connection under shear; the simplified simulation results and the test results were compared and analyzed, the applicable scope of each simplified model was explored; the parameter analysis of SPR connection with different plate thickness ratios was completed, the simplified nonlinear finite element analysis method for SPR connection of CFS structure was proposed. The research results showed that the main shear failure mode of the SPR were that the rivet leg pulled out the lower steel plate and the rivet head shears off the upper steel plate; the SPR connection between the CFS members in the steel frame could be simplified and simulated by the constraint unit Pin or the fastener unit Fastener, the SPR connection between the steel frame and the panel could be simplified and simulated by the connector unit Cartesian or spring unit Spring2; the Cartesian connector unit could accurately simulate the load-deformation curve and shear performance index of the SPR connection with different plate thickness ratios, and the calculation efficiency was high, it should be preferred in the nonlinear finite element analysis of CFS structure.
