Abstract
The present paper investigates the suitability and effectiveness of fiber-reinforced polymers
(FRP) in strengthening and/or repairing unreinforced masonry infill walls in reinforced
concrete frames which are subjected to in-plane seismic/cyclic loading. For this purpose, a
detailed experimental program was conducted. Specimen geometry, test setup,
instrumentation, and a loading procedure that simulates earthquake loading are presented
in a detailed fashion. Results of experimental observations are discussed in the form of
load-displacement hysteretic loops and envelopes; column profiles; strain diagrams, and
wall shear distortion. The test results, in general, indicate that the use of glass FRP (GFRP)
sheets as strengthening materials provides a degree of enhancement to the infill wall,
upgrades its deformation capacity, and makes the wall work as one unit. These results thus
show great potential for externally bonded GFRP sheets in upgrading and strengthening the
infill walls under in-plane seismic loads. © 2007 ASCE.
