This Technical Guidance Note concerns the design of masonry walls that are subject to lateral loads i.e. they are being used as a cladding element. It will discuss the way in which the material is assessed against how it isbeing restrained and its geometry. All of these factors have an impact on the design of masonry walls as well as the mortar within them and the exposure conditions. This is discussed in Technical Guidance Note 27 (Level 1) and should be read in conjunction with this guide.
(This article was updated in October 2016 to reflect errata issued since its original publication.)
The three forms of masonry are brick, concrete block and stone. This note introduces the first two as they are the most common. Used as a form of cladding - at least for concrete and steel-framed structures in the UK - loadbearing structural masonry is still in use, and employed in the construction of low-rise buildings and soil-retaining structures.
This note focuses on the design of one-way-spanning concrete slabs to BS EN 1992-1-1 – Eurocode 2: Design of Concrete Structures – Part 1-1: General Rules for Buildings .
This note clarifies the term 'simple connection' by explaining its use when designing connections within steel frames. Additionally, guidance on different types of simple connection and the design checks that need to be carried out, is provided.
