Technical Guidance Note (Level 1, No. 22): Biaxial bending in columns

The subject of this guide is the design of non-composite steel beams to BS EN 1993-1-1 – Eurocode 3: Design of Steel Structures – Part 1-1: General Rules for Buildings. It covers both restrained and unrestrained rolled steel ‘I’ and ‘H’ beam sections. This is the first in the series of Level 2 guides and as such,the reader is assumed to be familiar with the concepts explained in relevant Level 1 Technical Guidance Notes. (This article was updated in October 2016 to reflect errata issued since its original publication.)

An introduction to ground bearing floor slabs, touching on the slabs' reinforcement by considering both historical use of mesh as well as current plastic and steel fibre reinfocement methods.
