Nowadays, Ultra-High-Performance Concrete (UHPC) is being widely applied although there is a vital need to meet the design requirements. The bond stress between Ultra-High-Performance Concrete and reinforcing steel bars is a major issue which should be considered while designing the UHPC structures. In fact, there are some parameters such as UHPC strength, additive materials like Nano-silica content, concrete cover, development length and reinforcing steel bar size, which are the most effective factors on the bond stress between UHPC and reinforcing steel bars, therefore, the accurate design equations are required to consider the effects of all mentioned parameters on the bond stress.
