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.

The application of stainless steel in buildings has been increased gradually with excellent life cycle cost for ensuring the sustainability in structures for the reduction of green house gas emission. Especially, the purpose of this paper is to investigate the structural behaviors such as ultimate strength, fracture mode and out of plane deformation, i.e., curling of single shear bolted connection of cold-formed austenitic stainless steel with two bolts (2×1 bolt arrangement). Plate thickness and end distance parallel to the direction of applied force are considered as main variables. The curling was also observed in the bolted connections with a long end distance and edge distance as the previous researches. Curling occurrence resulted in the change of fracture modes in connections with same bolt arrangement and end distance and ultimate strength reduction.
