| Abstract |
In this study, experiments with monotonic tensile loading have been performed to investigate the structural behaviors such as ultimate strength
and fracture mode of double shear cold-formed carbon steel two-bolted connection and four-bolted connection with varied end distances for
providing the basic data of domestic design specification draft for cold-formed carbon steel bolted connection. Main variables are bolt
arrangement (2 columns × 1 row and 2 columns × 1 rows) and end distance parallel to the direction of applied load. Specimens with two
bolts failed by block shear fracture. Four-bolted connection showed two types of fracture mode at test end such as block shear fracture and
tensile net-section fracture at test end. Moreover, test ultimate strengths were compared with those by current design specifications (Korean
Design Standard (KDS)/American Institute of Steel Construction (AISC), Eurocode 3 (EC3), Canadian Standards Association (CSA), American
Iron and Steel Institute (AISI), Architectural Institute of Japan (AIJ) and strength equations suggested by previous studies for carbon steel
bolted connection. |
