Shear Behavior of Reinforced Concrete T-Beams with Externally Bonded
Fiber-Reinforced Polymer Sheets

Abstract
This research studies the interaction of concrete, steel stirrups,
and external fiber-reinforced polymer (FRP) sheets in carrying shear
loads in reinforced concrete (RC) beams. A total of eight 600 mm
high T-beam tests are reported. Three types of FRP were applied externally
to strengthen the web of the T-beams: uniaxial glass fiber; uniaxial
carbon fiber; and triaxial glass fiber. The test results show that
FRP reinforcement increases the maximum shear strengths from 77.4
to 117.3% over beams with no FRP. The magnitude of the increased
shear capacity is dependent not only on the type of FRP, but also
on the amount of internal shear reinforcement. The FRP strains were
found to be uniformly distributed among the fibers crossing the concrete
shear crack. This paper also presents a design model based on the
failure mechanisms of the test specimens. Good agreement was obtained
between test and predicted results by using the proposed model.
