Abstract

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.
