Abstract
Non-loadbearing masonry walls, have a considerable capacity, from the fire perspective, to isolate part of the building's interior from flames, heat and the effect of smoke. This research focuses on quantifying the fire resistance of non-loadbearing masonry walls subjected to elevated temperatures. Masonry walls constructed with different joint profiles, material properties as well as geometries have been considered. The fire resistance of the walls under each category has been analyzed using a finite element model and compared with experimental fire resistance tests. The numerical model correlates with the experimental tests results. In terms of concrete masonry, novel lightweight made of 45% recycled glass and 10% metakaolin produced the highest fire resistance of 172 minutes, approximately 27 and 50 minutes greater than conventional lightweight and normal weight concrete masonry respectively. Rock wool, used as an insert in conventional normal weight concrete masonry walls produced the highest fire resistance of 185 minutes
