The purpose of this study is to investigate the ultimate behaviors of aluminum alloy bolted connections assembled with four bolts. Specimens for single shear bolted connections were tested and finite element analysis based on this test results was conducted. The validity of finite element(FE) analysis for predicting the structural behaviors such as ultimate strength, fracture mode and curling(out-of-plane deformation) occurrence was verified through the comparisons between test results and FE analysis results. It is known that the curling resulted in sudden strength drop. Moreover, FE models with free edge and restrained out-of-plane deformation for curled specimens are analyzed additionally, therefore, the influence of curling on the ultimate strength; strength reduction ratio is estimated.

The experimental research for single shear bolted connection of cold-formed stainless steel fabricated with two bolts (2×1 bolt arrangement) has been conducted by T.S. Kim etc. Plate thickness and end distance parallel to the direction of loading was considered as main variables. It is found that the curling occurred easily in bolted connections with a long end distance and thinner plate. In this paper, finite element analysis study has been performed in order to compare test results with the predicted results and to investigate in detail the ultimate strength and curling influence. Finite element analysis(FEA) procedures also were introduced. FE models of connections with restrained out of plane deformation were also simulated for comparison with the curled models. Therefore, the validation of FEA in predicting ultimate strength and curling behavior was verified and the strength reduction ratio caused by curling was estimated.
