Technical Guidance Note (Level 2, No. 23): Design of triangular timber trusses

This Technical Guidance Note describes the design and detailing of base plates – the primary means by which steel-framed structures transmit vertical loads into their foundations.

Until relatively recently, masonry was the major load bearing component in a building structure. With the advent of steel and concrete frame technologies, masonry has become a part of a building’s cladding envelope and as such is more prone to being exposed to lateral loads than vertical ones. 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 is being 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.

The subject of this guidance note is the design of reinforced concrete beams to BS EN 1992-1-1 – Eurocode 2: Design of Concrete Structures – Part 1-1: General Rules for Buildings. It covers the design of multispan beams that have both ‘L’ and ‘T’ cross section profiles. (This article was updated in October 2016 to reflect errata issued since its original publication.)
