홈페이지논문 초록 (Abstract)
Experimental study has been performed to investigate the structural behaviors of single shear bolted connections fastened with aluminum alloys (7075-T6). End distance parallel to the direction of applied force was chosen as a main variable. Somespecimens with a relative ly short end distance failed by typical shear-out fracture and curling (out-of-plane deformation) in the perpendicular direction to loadin g was also observed for the others with a long end distance. The curl ing caused a temporary strength drop during test and test ultimate strengths were compared with those predicted by finite element analysis results. The validity of finite element analysis (FEA) for pre dicting the structural behaviors of bolted connections was verified an d strength reduction ratio by curling was estimated quantitative ly.
