Unbonded FRP to Improve the In-Plane Performance of Masonry Panels

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

Bonded fibre-reinforced polymer (FRP) strengthening has become a popular method for retrofitting masonry structures, but it is accompanied by onerous surface preparation and large quantities of polymeric adhesive. Both have health and safety implications, can be undesirable on a heritage structure, and the resulting adhesive joint is brittle. This paper reports on preliminary demonstration tests that investigate the use of unbonded FRP ‘bandages’ to increase the in-plane shear performance of masonry panels. It demonstrates that the elastic deformation of the FRP can be matched to the crack opening to increase the deformation capacity, ductility, and the load capacity of the masonry.
