These panels are quite slender to the point where they usually require additional horizontal support to make them stable. The same can also apply to cavity walls, where both skins are incapable of resisting lateral loads.
The element that provides this support to masonry panels is a vertical prop known as a ‘windpost’. Its principal role is to provide lateral support against destabilising horizontal forces that typically originate from wind pressure – hence, the name.
Windposts are typically steel elements – either open sections, such as channels or angles, or closed sections, such as rolled hollow rectangular sections. This Technical Guidance Note provides guidance on the design and detailing of windposts relating to their incorporation into building structures.
This note covers the inspection of structural elements typically present within buildings during their construction and/or alteration phases.
Base plates are the primary means by which steel-framed structures transmit vertical loads into their foundations.
This note concerns the design of masonry walls subject to lateral loads (i.e. those used as a cladding element). It discusses material assessment, restraint, geometry and exposure conditions. Updated in October 2016.
