| Abstract |
This study investigates the fracture patterns and ultimate strengths of the double shear two-bolted connections made of austenitic stainless steel
STS304, which is widely used in building structures. The main variables include the plate thickness and end distance in the loading direction.
A total of 10 test specimens were planned and fabricated. For specimens with relatively short end distance of less than 24mm, shear-out
fractures occurred, while, specimens with end distances of 36mm or more showed typical block shear fracture mode. The strengths of both
domestic and international design codes (KDS, AISC, AISI, ASCE, AIJ and EC3) and the equations of shear-out and block shear fractures
proposed by the previous researcher were compared with test results. The current standards underestimated the test strengths of double shear
two-bolted connections of austenitic stainless steel, and shear-out fracture and block shear fracture equations suggested by other researchers
based on carbon steel or duplex stainless steel bolted connections were found to provide good predictions. |
