Fatigue analysis of a UHPFRC-OSD composite structure considering crack bridging and interfacial bond stiffness degradations

This study presents a numerical method developed in a finite element model to analyze both the static and fatigue behaviors of the orthotropic steel deck (OSD) strengthened with an Ultra-High Performance Fiber Reinforced Concrete (UHPFRC) overlay under the wheel-type load. In static analysis, the factors that approach the real conditions of composite deck are investigated to achieve a balance between calculation accuracy and efficiency. Employing the model identified in static analysis, fatigue analysis of composite deck under a moving wheel load is conducted considering the bridging degradation of cracked UHPFRC and the bond stiffness degradation at the UHPFRC/steel interface. From a good reproduction of the experimental behaviors, it may be indicated that the assumed scenarios regarding the interfacial degradation were what happened in the experiment. Consequently, the numerical model can provide a deeper understanding of the current experiment in terms of the fatigue performances as well as the deterioration mechanisms.
