Abstract

The fabricated cylindrical pipes are widely used as the column member, since they have effective shape for axial load. Cylindrical pipes have the circumferential residual stress that occured in the fabricated process of the cold-forming work. Additionally, this process gives much effect on the increasing of the yield stress of material, due to strain hardening. In this report, the column strength of cylindrical tubular members that have variable radius-tothickness ratio is analyzed considering circumferential residual stress and increasing of yield stress which are calculated by the proposed equations considering fabricated process.
