Evaluation of the bond behavior at the intermediate crack element with a special test procedure
- The bond behavior of externally bonded reinforcement is one main parameter for the load bearing capacity of strengthened reinforced concrete structures. Because of the low bond force transfer at the outmost bending crack, the bond forces have also been transferred to elements between the cracks in order to effectively utilize the permissible stress of the CFRP strip. Two different experimental series on the bond behavior on the intermediate crack element were carried out. Small tests on an idealized intermediate crack element were made to evaluate the bond stress increase. In the second series parts of a structural element, which had the length of an intermediate crack element were tested to find out about other effects which only occur in the structural element. Based on these experimental data and the differential equation of the sway bond a new concept for the bond behavior of externally bonded reinforcement has been found out.
