This poster summarises our Honours research on retrofitting heritage listed unreinforced masonry structures with carbon fibre reinforced polymers (CFRP).
More specifically, we experimentally performed 15 single shear pull tests on masonry bricks; 5 of which were retrofitted with a CFRP plate, 5 with a mechanical anchor and 5 retrofitted with both. A numerical analysis was undertaken using what's known as the 'Partial interaction model'. This successfully modelled the experimental load-slip behaviour recorded for the series retrofitted with both the plate + anchor.
Lastly, we used the aforementioned information and developed a load displacement model for a retrofitted wall. This involved capturing principles of rigid body motion, geometry and statics and is a simplified approach for the analysis of the wall for a 1 strip FRP retrofit.
