BOND BEHAVIOR BETWEEN CFRP SHEET AND CONCRETE (PART 1)

Bond between Cfrp Sheets and Concrete

This paper presents the findings of an experimental program aimed at investigating the strain distribution between Carbon Fiber Reinforced Polymer (CFRP) sheets and concrete. CFRP is used as externally bonded reinforcement for concrete structures to improve flexure and shear strength and confinement of concrete. The effects of bonded length, concrete strength, and number of plies (or stiffness)...

Monotonic and Cyclic Bond Behavior of Deformed CFRP Bars in High Strength Concrete

Composite reinforcing bars (rebars) that are used in concrete members with high performance (strength and durability) properties could have beneficial effects on the behavior of these members. This is especially vital when a building is constructed in an aggressive environment, for instance a corrosive environment. Although tension capacity/weight (or volume) ratios in composite rebars (carbon ...

Bond Behavior of Cfrp Strengthened Steel Structures

Recent research has focused on rehabilhation and strengthening of steel structures and bridges using fiber reinforced polymer (FRP) materials. The bond behavior of FRP materials to steel structures is quite different from lhat of concrete structures. Preliminary test results showed the occurrence of very high bond stresses for most strengthening applications due to the amount of strengthening r...

The Effect of Elevated Temperature on the Bond between High Modulus CFRP Sheet and Steel

The technique of strengthening steel structures with Carbon Fibre Reinforced Polymer (CFRP) has attracted growing attention in research field and in practice and its environmental durability is of high importance. This paper describes an investigation on the bond characteristics between high modulus CFRP sheet and steel plates under elevated temperature exposures. Tensile tests were carried out...
