Abstract: The bond characteristic between reinforcing bars and concrete can have a significant influence on the specific deflection and cracking of the entire structure. In case of a seismic event, the structure and thus the main reinforcement is cyclically loaded. At the same time, cracks along the reinforcement anchorage open and close due to the cyclic response of the structure. Both phenomena progressively damage the bond strength. The effect of simultaneous acting cyclic load and crack was experimentally investigated at the Laboratory of the University of Stuttgart to determine a bond stress-slip model.
