Bonded and reinforced concrete overlays are widely used for precast elements, which receive an in-situ overlay. The performance of such overlays relates mainly to the concrete-to-concrete bond. The regulations of the German annex of Eurocode 2 for 'shear at the interface between concrete cast at...
An experimental study was performed to determine the environmental durability of the adhesive bond between fiber-reinforced plastic (FRP) and concrete. The study specifically focused on freeze-thaw cycling exposure of such bonds and their ultimate strength prior and after the environmental exposure. To...

structure by affecting the development and transfer lengths of the reinforcement (respectively defined as the minimum embedded length demanded to develop the ultimate tensile strength of the bar [35], and as the length over which the prestressing force is totally transferred to the concrete [36])....
Concrete-encased composite structure exhibits improved strength, ductility and fire resistance compared to traditional reinforced concrete, by incorporating the advantages of both steel and concrete materials. A major drawback of this type of structure is the bond slip introduced between steel and concrete...
Bond strength of fibre reinforced polymer (FRP) rebars was experimentally investigated in this study and compared to that of steel rebars. A total of 64 concrete beams reinforced with two types of FRP rebars, respectively, were tested. Four nominal diameters of FRP and steel rebars, namely, 12....

to domestic and foreign experiments,authors proposed that when the thin-walled concrete damaged,the sample was destoryed.Base on this principle,a semiemprical theory formula was deduced using elastic mechanics and material mechanics methods.Analytical results show that bond strength of concrete-filled ...
A bond element is presented for use in high-resolution finite element modeling of reinforced concrete structures subjected to general loading. The model is defined by a normalized bond stress versus slip relationship and a relationship between maximum bond strength and the concrete and steel stress-...
