Abstract
The successful application of composites for structural upgrade has
motivated the development of other novel low-cost reinforcement systems
that exhibit excellent structural properties. The ability to put very high tensile
strength steel into a fabric that can be incorporated into composites was one
of the particular interests to the engineering communities worldwide.
This Thesis examines the feasibility and potential of using high-strength steel
reinforced polymers (SRP) to strengthen reinforced concrete beams.
A total. of seven concrete beams (150x300x3000 mm) were constructed
and tested under four point bending to evaluate the effectiveness of the
strengthening scheme. The influence of the type of the bonding agent number of plies and the arrangement of the U-wraps along the length of the
concrete beams is investigated. Test results showed that SRP could improve
both the flexural stiffness and the ultimate load carrying capacity
considerably. The flexural capacity was increased by more than 300% using
multiple plies of SRP sheets. For the majority of the tested beams, failure was
primarily controlled by delamination of the sheets from the concrete surface.
Using U-wraps along the length of the beam prevented this type of failure
and allowed full utilization of the tensile strength of the sheets .
