چکیده
This paper reports an experimental study on the behavior and shear strength of concrete beams reinforced with longitudinal GFRP bars mixed sea water. In order to evaluate how much contributes resistance, seven were tested in bending. Similar size strength, longitudinally glass fiber-reinforced polymer bars; however, they did not even have reinforcement. The beams, which measured 3,100 mm length, 400 depth, 200 width, conducted up failure. test variables reinforcement ratios (1.0, 1.4, 2.0%), chopped fiber content (0, 0.5, 2, 3 kg/m3), mixing water type (freshwater seawater). findings showed that increasing ratio increased neutral-axis depth allowed formation more closely spaced fractures while decreasing loss flexural stiffness after cracking. By area compression, this turn enhances contribution aggregate interlock as well uncracked concrete. Furthermore, improves dowel action, reduces tensile stresses are created around it.

Flexural Behavior of Lightweight Concrete Beams Reinforced with GFRP Bars and Effects of the Added Micro and Macro Fiber
This study evaluated the effect of macro steel fiber (SF), micro glass fiber (GF) and micro polypropylene fiber (PF) in lightweight aggregate concrete, (LWAC) beams reinforced with glass fiber reinforced polymer (GFRP) bars. Firstly, concrete mixtures with different volume fractions of GF, PF and SF were tested up to compressive strength, then determine the optimum fiber content GF, PF and SF a...
متن کاملStepwise Regression for shear capacity assessment of steel fiber reinforced concrete beams
The addition of steel fibers into concrete improves the postcracking tensile strength of hardened concrete and hence significantly enhances the shear strength of reinforced concrete reinforced concrete beams. However, developing an accurate model for predicting the shear strength of steel fiber reinforced concrete (SFRC) beams is a challenging task as there are several parameters such as the co...
متن کاملShear strengthening of reinforced concrete beams with CFRP
The current paper reviews existing design guidelines for strengthening beams in shear with carbon fibre reinforced polymer (CFRP) sheets and proposes a modification to Concrete Society Technical Report TR55. It goes on to present the results of an experimental programme which evaluated the contribution of CFRP sheets towards the shear strength of continuous reinforced concrete (RC) beams. A tot...
متن کاملRetrofitting of Reinforced Concrete Beams with Steel Fiber Reinforced Composite Jackets
In the present study, a new method for retrofitting reinforced concrete beam is introduced in which steel-concrete composite jackets containing steel fiber is used. For this purpose, 75% of the peripheral surface of reinforced concrete beams was initially reinforced using steel plates and bolts, and steel fiber reinforced concrete was used between the steel plates and the peripheral surfaces of...
