To investigate the influence of repeated loading on bond behavior between steel bars and reactive powder concrete (RPC), this study conducted tests eight beam specimens one static test as a control. The effects stress levels number cycles RPC were examined. results indicate that failure mode was characterized by bar pull-out accompanied significant plastic deformation, with no propagation cracks in after their initiation, demonstrating excellent crack control capability RPC. After 10,000 at high level (Z = 0.9), ultimate strength decreased only 3.68%, indicating superior fatigue resistance steel–RPC interface. Based analysis slip accumulation effects, constitutive model considering established. This can serve basis for design anchorage structures subjected to cyclic loading.
