Assessment of Perforated Unreinforced Masonry Walls Responding In-Plane
… assessment of perforated unreinforced masonry (URM) walls subjected to in-plane loading through accurate analysis of the wall lateral capacity and seismic demand. Current assessment methods for determining the capacity of perforated URM walls loaded in-plane, as outlined in the New Zealand …

Seismic Performance of Unreinforced Masonry Walls Retrofitted with Post-tensioning Tendons
Unreinforced masonry (URM) structures have historically been regarded as structurally unsound in response to seismic events. The tendency for URM walls to collapse out-of-plane in a brittle manner is continually cause for concern. Retrofit of these walls is necessary in order to prevent severe …

Retrofitting unreinforced concrete masonry to resist tornado loading
… of these structural failures, buildings with walls of Unreinforced Masonry (URM) are incapable of withstanding the magnitude of forces brought on by a tornado, and the cracking or failure of just one wall can lead to the progressive collapse of the entire structure. The need to reinforce these …

Increasing the Blast Resistance of Concrete Masonry Walls Using Fabric Reinforced Cementitious Matrix (FRCM) Composites
Unreinforced masonry (URM) walls are often used as load-bearing or infill walls in buildings in many countries. Such walls are also commonly found in existing and heritage buildings in Canada. URM walls are strong structural elements when subjected to axial loading, but are very vulnerable under …

Blast Retrofit of Unreinforced Masonry Walls Using Fabric Reinforced Cementitious Matrix (FRCM) Composites
Unreinforced masonry (URM) walls are commonly found in existing and heritage buildings in Canada, either as infill or load-bearing walls. Such walls are vulnerable to sudden and brittle failure under blast loads due to their insufficient out-of-plane strength. The failure of such walls under blast …

Optimization of timber-based strengthening techniques for the seismic retrofit of existing masonry buildings
… and energy retrofit of unreinforced masonry (URM) buildings considering various case scenarios and evaluating both the mechanical and the energetic performance of the intervention. Timber engineered products were employed as base components for the retrofit intervention. The products include …
