Concrete Design Guide. No. 6: Fire design of concrete columns and walls to Eurocode 2

Strut-and-tie modelling is a simple method of modelling complex stress patterns in reinforced concrete as triangulated models. This article is an introduction for engineers who want to take advantage of this useful analysis method.

This short note highlights some of the salient aspects of the design and construction of liquid-retaining structures in reinforced concrete. The guidance is based on Eurocodes BS EN 1992-1-11 and BS EN 1992-32 and the corresponding UK National Annexes.

The design for horizontal actions, fire and materials is considered, along with simplified methods of design. Throughout this article the Nationally Determined Parameters (NDPs) from the UK National Annexes have been used. These enable Eurocode 6 (BS EN 1996-1-1) to be applied in the UK.
