| Abstract |
In this paper, experimental study has been performed to investigate the structural behaviors of cold-formed lean duplex stainless steel
(STS329FLD) single shear and double shear bolted connections with single bolt and two bolts for providing the basic data of domestic design
specification for stainless steel structure. Main variables are shear connection type (single shear and double shear), end distance parallel to the
direction of applied force and number of bolts (single bolt and two bolts). Specimens with single bolt failed by shear-out fracture except for
some specimens with bolt shear fracture and two-bolted connection showed shear-out fracture at test end. Curling, i.e., out of plane deformation
in the direction of plate thickness occurred in single shear two-bolted connections and it led to ultimate strength reduction. Moreover, test
strengths were compared with those by current design specifications (Korean Design Standard (KDS)/American Institute of Steel
Construction(AISC), Eurocode 3(EC3), American Society of Civil Engineers(ASCE) and American Iron and Steel Institute(AISI)) and strength
equations suggested by previous studies. |
