The design of timber elements in the UK, according to current codes of practice, is based on limit state theory. This Technical Guidance Note adopts this approach to describe the design of timber posts. The note assumes that the reader is familiar with the use of coefficient factors prevalent within BS EN 1995-1-1 (Eurocode 5), as described in Technical Guidance Notes Level 1, No. 18 Design of timber floor joists and Level 2, No. 14 Design of unrestrained timber beams.
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.
This note explains how reinforced concrete walls are designed to withstand high in-plane bending forces, in accordance with Eurocode 2.
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.
