Because of additional live loads or modifications of the building structure these slabs often have to be strengthened. Using externally bonded carbon-fiber reinforced polymer (CFRP) strips to strengthen existing concrete structures has become common practice. One of the main failure modes is the loss of the composite action between the concrete and the CFRP strip making the bond force transfer very important. This bond force transfer depends on many parameters including the concrete strength, the ratio between shear force, and bending moment. A new parameter recently discovered by the Technische Universit{\"a}t M{\"u}nchen (TUM) is the deflection of the structural elements themselves. Because of this deflection self-inducted contact pressure occurs. This contact pressure affects a higher bond transfer. The lower effective depth of slabs compared to beams causes higher deflections. In this article, first a few principles on the strengthening with adhesive-bonded CFRP strips and the characteristics of the bond are explained. Then, the basics of the bond force transfer, at the end anchorage and in the rest of the element, are summarized. Based on these essentials, as well as numerous experiments, the change in the bond force transfer at the structural element caused by the curvature is then derived. With these findings, a complete verification concept is presented, which is ideal for computerized calculations. This verification concept is finally compared to several full-scale test results presented in pertinent literature.}, language = {en} } @book{ZilchNiedermeierFinckh, author = {Zilch, Konrad and Niedermeier, Roland and Finckh, Wolfgang}, title = {Verankerung von aufgeklebten Stahllaschen im Bereich von Biegemomenten mit wechselnden Vorzeichen}, publisher = {Fraunhofer IRB Verlag}, address = {Stuttgart}, isbn = {978-3-8167-8821-8}, abstract = {Bei durchlaufenden verst{\"a}rkten Stahlbetonkonstruktionen kann es aufgrund der ung{\"u}nstigen Anordnung der Verkehrslasten im Bereich der Verankerung der aufgeklebten Bewehrung zu einem Vorzeichenwechsel des Momentes bei unterschiedlichen Lastf{\"a}llen kommen.

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.}, language = {en} } @inproceedings{FinckhZilch, author = {Finckh, Wolfgang and Zilch, Konrad}, title = {Evaluation of the bond behavior at the intermediate crack element with a special test procedure}, series = {Advances in FRP Composites in Civil Engineering : Proceedings of the 5th International Conference on FRP Composites in Civil Engineering (CICE 2010), Sep 27-29, 2010, Beijing, China}, booktitle = {Advances in FRP Composites in Civil Engineering : Proceedings of the 5th International Conference on FRP Composites in Civil Engineering (CICE 2010), Sep 27-29, 2010, Beijing, China}, editor = {Ye, Lieping and Feng, Peng and Yue, Qingrui}, publisher = {Springer}, address = {Berlin ; Heidelberg}, isbn = {978-3-642-17486-5}, doi = {10.1007/978-3-642-17487-2_111}, pages = {517 -- 520}, abstract = {The bond behavior of externally bonded reinforcement is one main parameter for the load bearing capacity of strengthened reinforced concrete structures.
