In this study, the effect of stiffeners on the low cycle fatigue life of steel H-piles in integral bridges is investigated to prevent local buckling occurring at high strain amplitudes. For this purpose, experimental testing of a number of regular and stiffened steel H-piles under cyclic displacement reversals is conducted. Then, to compare experiment results with the finite element model for the HP220x57 steel specimen, finite element model is constructed similarly according to actual HP220x57 steel specimen in the test set up
