Fiber reinforced polymer (FRP) materials are continuing to show great
promise for use in strengthening reinforced concrete (RC) structures.
These materials are an excellent option for use as external reinforcing
because of their light weight, resistance to corrosion, and high
strength. Externally bonded FRP sheets have been used to increase
moment capacity of flexural members and to improve confinement in
compression members.
Investigations into the use of externally bonded FRP sheets for use
in shear strengthening have also been conducted and have shown this
to be a viable strengthening method. The objective of this study
is to review the current research on shear strengthening with FRP
and propose design algorithms to compute the contribution of FRP
to the shear capacity of RC flexural members. Methods for computing
the shear capacity based on the stress level to cause tensile fracture
of the FRP sheet (which may be less than ultimate due to stress concentrations)
and based on delamination of the sheet from the concrete surface
are presented. Areas which have the potential for further development
are also discussed.
