Our study utilizes a range of cumulative fatigue damage models to better understand the
behavior of high-strength steels, addressing some of the shortcomings in current methodologies.
To achieve this goal, a series of mechanical tests were performed on two types of HSS, S690, and
S960, to understand the properties of these materials and determine their effect on the ability
to resist fatigue damage. The accuracy of each model is determined based on the fatigue tested
and S-N curves formed. The results are analyzed to determine which models are appropriate
for predicting the fatigue behavior of high-strength steels. Overall, this study provides valuable
insight into the fatigue behavior of HSS and highlights the need for further research in this
area. By expanding our understanding of the properties of HSS, we can continue to develop
new and innovative ways to utilize this material in construction, ultimately leading to safer
and more reliable structures.
