Historically, masonry walls were designed as principal loadbearing elements of a structure. They were very thick and were able to withstand lateral loads due to their stocky geometry. Today, however, the status of brick walls within large buildings has been reduced to that of simple single-skin rainscreens that are little more than large thin panels of masonry.

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.

<h4>Technical Guidance Note (Level 2, No. 9): Designing a reinforced concrete retaining wall</h4>

Technical Guidance Note (Level 2, No. 9): Designing a reinforced concrete retaining wall

Although retaining walls have been the subject of two earlier Technical Guidance Notes; No. 8 (Level 1): Derivation of loading to retaining structures and No. 33 (Level 1): Retaining wall construction, their design has not been covered. This guidance note focuses specifically on the design of reinforced concrete gravity retaining walls. There are three different forms of this type of wall, all of which are designed to resist overturning and sliding failure. The primary difference between them is their height. The taller the retaining wall, the more likely that counterforts and beams spanning between them will be necessary. This note describes how all of these forms of retaining wall can be designed. (This article was updated in October 2016 to reflect errata issued since its original publication.)

<h4>Technical Guidance Note (Level 2, No. 12): Introduction to steel portal frames</h4>

Technical Guidance Note (Level 2, No. 12): Introduction to steel portal frames

Portal frames are a simple and very common type of framed (or skeleton) structure. Steel portal frames, in particular, are a cost-effective structural system to support building envelopes requiring large column-free spaces. This Technical Guidance Note gives an introduction to steel portal frames and their preliminary analysis.
