The bond forces must be transferred where the load is applied. These bond forces may be transferred by the elements in between flexural cracks which are mainly influenced by the bond behavior of the internal and external reinforcing. Therefore the models which were derived from end anchorage tests must be expanded to include other effects as well. These models were first described theoretically by the differential equation of bond and a bilinear bond stress slippage relationship. To evaluate this theoretically derived relationship numerous experiments on the intermediate crack elements where conducted. In this paper, an evaluation of these experiments in two different ways is shown. The one evaluation is carried out only on the fracture force, the other analysis also takes the slippage occurred in the intermediate crack element tests into account. With both evaluations it can be shown, that besides the previously scheduled bilinear bond approach additional friction effects between the already decoupled fracture surfaces of the bonded strips occur.

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.
