Steel structures subjected to earthquakes or extreme cyclic loadings may undergo extensive damage and fractures due ultra-low-cycle fatigue (ULCF). Although assessments of initiation evolution parameters have been carried out for some steels exposed low-cycle fatigue, so far, these structural ULCF neither sufficiently studied nor quantified. Accordingly, this paper provides the results finite element analysis (FEA) concerning behaviors S355 S690 steel specimens. Calibration is performed in SIMULIA Abaqus 6.11 FEA software using a direct algorithm available experimental data. Kliman’s model hysteresis energy loading used analytically verify parameters. In addition, data were obtained from axial strain tests on specimens according ASTM International standard E606/E606M-21. Finally, non-linear Chaboche–Lemaitre (C–L) combined isotropic–kinematic hardening characterization behavior simple cylindrical bar. It found that two are 5.0 −0.8, first parameter dominant when modeling number cycles failure, second material constant.
