Abstract
In this study, tensile and compression tests of specimens that were taken from the SNT355E electronic resistance welded(ERW) pipe were conducted to compare the difference of each behavior. Four-point bending test and finite element analysis for the SNT355E pipe were performed to investigate the effect of stress-strain relationships that are influenced by pipe forming process and to propose an exact flexural performance estimation process for a ERW steel pipe. Furthermore, parametric study was conducted to investigate the effect of D/t ratio and the change of yield ratio on the bending performance of steel pipe through load-displacement curves, displacement ductility ratio and ductility factors. It was confirmed that both the tensile and compression behavior should be considered to exactly estimate the flexural performance of a ERW steel pipe, and the ductility performance of a ERW steel pipe is more influenced by D/t than yield ratio.
