Strain capacity is required for line pipes used in strain based design (SBD) applications. This paper deals with the buckling resistance of UOE line pipes under the bending moment, and discusses the methodology for evaluating the strain capacity. The critical condition, in which the compressive strain limit is minimized, was found by modeling the geometric imperfection of a pipe with the strength distribution under the bending moment. Comparing the minimum strain limit with the prediction by the single stress-strain (S-S) curve, the sampling position was optimized. The higher correlation to the strain limit was obtained by sensitivity analysis using the measured S-S curves. Consequently, reliable methods have been suggested for SBD.
