홈페이지논문 초록 (Abstract)
In the study, experimental study has been performed to investigate the mechanical behaviours such as ultimate strength and fracture mode of single shear bolted connections with aluminium alloy 7075-T6. Main variables are bolt arrangement and end distance. As a result, the specimens failed by shear-out fracture and block shear fracture. Some specimens with a long enddistance were accompanied by curling ( out of plane deformation). The curling led to a sudden ultimate strengt h reduction. Moreover, the change of strain distribution was inves tigated according to curling occurrence. The reliability of design rules for single shear bolted connection in AAA, AISI and AIJ specificatio n is evaluated through comparison between test results and prediction s by each current design standard. Lastly, the strength equations considering curling effect and boltarrangement were propose d and compared with test results.
