ABSTRACT
The use of increased levels of insulation within masonry veneer walls places increased demands on the gravity support systems including exposed slab edge, edge-connected steel angles, and discretely connected steel angles. In addition to structural and durability criteria, designers also need to assess masonry gravity support systems for thermal continuity and thermal bridging.
This paper examines and summarizes the essential thermal design criteria related to masonry veneer gravity support systems. The results from three-dimensional thermal modelling of typical masonry veneer gravity support systems is presented to illustrate the impact of thermal bridging and the inherent benefits of de-coupling masonry supports from the building structure.
This paper will prove useful to both masonry contractors and designers responsible for the construction or design and detailing of masonry veneer gravity support systems.
