This paper investigates
experimentally how various bond
configurations influence the
flexural response
of FRPstrengthened
RC beams. A total of seven beams(200×200×2200mm) were
tested. One was the reference without strengthening. Two were strengthened with
CFRP sheets using hard and soft adhesive bonding, respectively, along the whole
test span. The remaining four were applied a combination of hard and soft
adhesives but in two different ways. One way is to use the soft adhesive at the
flexure-dominating zone only and another is to use it for the sheardominating
zone only. Pair tests were conducted for these four specimens under both normal
and low temperature (- 10°C). It is revealed that a sole use of soft adhesive
improves the ultimate member strength and ductility but leads to
