-The fatigue properties of the S690 steel were assessed with a lower scatter than resulted for the S355 steel,which means higher quality of the high strength steel with respect to the mild steel.-Despite the fact that strain-life data have shown a better fatigue performance of the S355 steel for low-cycle fatigue regimes,this result may not A Deformation History-Based Approach for Ultra-Low Cycle Ultra-low cycle fatigue (ULCF) damage is one of the main failure modes of steel structures when subjected to intense earthquake action,such as near-field action.However,existing ULCF evaluation methods are based on the plastic strain history of structures,which requires fine numerical simulation and causes high calculation cost.In order to improve and simplify the ULCF evaluation process
