Introduction
Since the invention of medium-storey framed structures in the late 1800s, there has been a need to clad them with a reasonably robust material that acts as an efficient barrier to the external environment. Masonry delivers the performance required of a cladding system on multiple fronts. It has therefore developed from a load-bearing element within structures to become a component of an envelope to larger framed buildings.
This Technical Guidance Note introduces structural engineers to the interfaces between a primary structure that is principally formed from steelwork and a masonry cladding system.
