Flexural Capacity Of Rc Beams With Externally Shear Strengthening Using Gfrpsheet
Abstract
Combination of several materials to create a structural system has led to new kinds of innovative infrastructure
applications. The addition of Glass Fiber Reinforced Polymer(GFRP) laminated bonded to the tension face of concrete
member is an attractive solution to the rehabilitation and repairing damage structural for example : bridge girder and beam
building construction. To increase the shear strength , the externally bonded GFRP wrap can be applied continuously or
discontinuously (strips) to a beam in general wrapping scheme:�U� wrapping, or fully wrapping. The aim of this study is to
investigate the flexural capacity RC beams of shear cracked by using GFRP as a external strengthening . The fiber of GFRP
sheets are placed in one layer (shear strengthening using continuously �U�wrapping ). The test specimen were designed to
shear failure in which shear span - to effective depth ratio is 1.56 and stirrups were spaced at a distance of 300mm. All
specimens were tested under two-point static loading, the beam were incrementally loaded to failure. It is found that that
externally bonded GFRP sheet can enhance the flexural capacity and also can change failure mode from shear-crack become
flexural failure of RC beam.
