•Reference stress approach cannot be applied directly to submarine pipelines under strain-controlled conditions. The nominal stress was acquired using the derived implicit equation, f(σn, εn) = 0, according to the relationships among the true stress, true strain, nominal stress, nominal strain, and Ramberg–Osgood's constitutive model. Therefore, the input parameter P in reference stress approach can be acquired through the implicit equation.•Reference stress approach comes from EPRI approach by the assumption that h(n) = h(1), and this will sacrifice the accuracy. A γ factor was used to modify the limit load solution in order to increase the accuracy. A regression analysis of γ based on finite element analysis was executed.•The reference stress approach was modified through γ factor and the empirical formula of γ was acquired.•Results of the modified reference stress approach through γ proved to be more close to FEA. |
