 Abstract
Many researchers have studied the structural performance of bolted connection with aluminum alloys and design specifications for in-plane fracture (net-section, bearing and block shear fractures) of bolted connection have been improved by their study results. However, it can be known from study results conducted by Kim et al. that curling (out-of-plane deformation) could be negative effect (strength reduction) on ultimate strength of single shear bolted connection fabricated with 3.0mm thick aluminum alloy(6061-T6) plate. Strength reduction for curled single shear specimens obtained from the comparison of test results for double shear bolted connections ranged from 4% to 30%. In this paper, additional experiments are performed in order to investigate the influence of curling on ultimate strength and curling occurrence condition for 4.0mm thick bolted connection. Main variables are end distance and edge distance. In all specimens, strength reduction by curling was observed. Strengths obtained from test results were compared with design strengths predicted by AISI (American Iron and Steel Institute) and AAA (American Aluminum Association) design rules. Bearing factor considering curling effect and hole deformation limit was discussed.
