Flexural Fatigue Behavior of UHPFRC and R-UHPFRC – RC Composite Slabs

---

The aim of this study is to investigate the flexural fatigue behavior of UHPFRC, R-UHPFRC and R-UHPFRC – RC under biaxial stress state with a comprehensive experimental program.

There are several issues proposed to be addressed as follows :

1. To understand the biaxial flexural fatigue behavior of UHPFRC and R-UHPFRC slabs (including at very high fatigue cycles)
   
   
2. Correlation between the uniaxial and biaxial flexural fatigue behavior
   
   
3. To understand the biaxial flexural fatigue behavior of RU-RC members
   
   
4. To develop empirical models for the biaxial flexural fatigue behavior of UHPFRC and R-UHPFRC slabs
   
   
5. To establish design rules and safety concept for the biaxial flexural fatigue behavior OF RU-RC members.
