Abstract
This paper presents experimental work undertaken at the
Centre for Cement & Concrete of the University of Sheffield
on the short term behaviour of Reinforced Concrete (RC)
beams strengthened either by epoxy bonded Carbon Fibre
Reinforced Polymers (CFRP) or steel plates. It is shown that
external bonding of CFRP plates can be used as an
alternative to steel plates to achieve satisfactory repair or
strengthening of existing RC beams, especially in enhancing
their serviceability limit states. An innovative anchorage
technique requiring no end fixings was developed during this
research work. Experimental results demonstrate the
effectiveness of this technique in avoiding or delaying
peeling off of the external plate from the strengthened RC
beam.
