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.
Base plates are the primary means by which steel-framed structures transmit vertical loads into their foundations.
This note focuses on the design of columns in simple construction to BS EN 1993-1-1 – Eurocode 3: Design of Steel Structures – Part 1-1: General Rules for Buildings . It covers rolled steel ‘I’ and ‘H’ sections acting as columns within a braced steel frame structure.
