Abstract:

In order to introduce self-piercing riveting (SPR) with high connection efficiency and industrialization into cold-formed thin-walled steel structure, the tension tests for 84 groups of SPR by thin-walled steel sheet were conducted. The steel sheet thickness, thickness ratio, combination detail of steel sheet and rivet length were discussed for their effects on tension property and failure mode of SPR. The applicability of the existing calculation methods of tensile strength of SPR and the design methods of tensile capacity of self-drilling screw in various specifications was also investigated. The research also proposed calculation method of tension capacity of SPR and design method based on the allowable strength design. The results show that the thickness ratio (t2/t1) was a key factor affecting the failure mode of SPR, and pull-out of rivet tail from the bottom steel sheet occurs for 1≤t2/t12/t1≥1.5. Steel sheet thickness and rivet length have significant influence on tensile properties, and the tension capacity increases linearly with the increase of both. Combination detail of steel sheet has a great influence on the tensile properties and failure modes, and the thinner sheet in contact with rivet head could effectively improve tension capacity and deformation capacity. Since the calculation results are too conservative and the failure modes cannot be considered comprehensively, the existing calculation methods are not suitable for SPR in cold-formed thin-walled steel. Compared with the existing methods, the design method proposed in this paper for tension capacity of SPR could include more comprehensive failure modes, with higher calculation accuracy. © 2020, Editorial Office of Journal of Building Structures.
