This paper is focused on the structural behavior of the single shear bolted connections with thin-walled ferritic stainless steel. The purpose of this study is to investigate the ultimate behaviors, s uch as ultimate strength and fracture mode of the single shear bolted connections of thin-walled ferritic stainless steel (low cost steel) rather than austenitic stainless steel (high cost steel). Bol t arrangement and end distance parallel to the direction of app lied load are considered as main variables of the test specimens for bo lted connections. Specimens have a constant dimension of edge dist ance perpendicular to the loading direction, bolt diameter, pitch, and gauge. A monotonic tensile test for specimens has been carrie d out and some bolted connections with long end distance showed curling (out of plane deformation) occurrence whichled to strength reduction . The ultimate behaviors such as fracture mode, ultimate strength a re compared with thosepredicted by current design codes. Furthe r, conditions of curling occurrence and the strength reduction d ue to curling are investigated and modified strength equations are suggested considering the curling effect.
