Experimental investigation for anti-slipping performance of stainless steel slip-resistant connections with particles embedded in connected plates

Stainless steel has significant potential in high-durability structural applications owing to its superior corrosion resistance. However, efficient fastener connections similar to slip-resistant connections are lacking in stainless steel structures. Conventional treatments fail to obtain sufficient slip factors on stainless steel plates owing to the passive film on its surface. This paper proposes an innovative anti-slipping concept using particles embedded in the stainless steel plate surface. Static experiments illustrate that S45990 stainless steel beads with diameters of 2 mm can be applied to 5-mm-thick S30406 stainless steel plates. The ultimate slip factor of connections with seven beads and one preloaded stainless steel A4-80 bolt is 1.4.
