FRP composite materials are widely applicable in the construction industries as a load-bearing structural element or a reinforcing and/or repairing materials for the concrete. In this paper, we presented the flexural behavior of steel reinforced concrete beams reinforced with FRP re-bars manufactured by different fibers but the same vinylester resin. Experimental investigation pertaining to the load-deflection and load-strain characteristics of steel reinforced concrete beams reinforced with FRP re-bars with garnet coated surface is presented and the theoretical prediction is also conducted. In the investigation, the effects of FRP re-bar reinforcement in addition to the steel reinforcement are estimated. The experimental results are compared with theoretical predictions. Good agreements are observed.

Current Standards

Bond-slip performance between section steel and concrete has influence on deformation of steel reinforced concrete beams based on results of experimental studies. Current standards on steel reinforced concrete structures do not involve bond-slip effects when calculating the deflection of steel reinforced concrete beams and this is not valid exactly. This paper describes a new method of deflection calculation for steel reinforced concrete beams, which considering the bond-slip effects on deformation. Deflection of steel reinforced concrete beams are divided into two parts: deflection of steel reinforced concrete beams under loads considering the fully bond between steel and concrete, and the additional deflection caused by the bond-slip. The sum of the two parts is the total deflection. Results show that the proposed method in this paper fits with experimental results.
