Be careful how you use finite element analysis Friday, 22 August 2014

Finite element analysis (FEA) packages for the design of concrete buildings have become useful tools for structural engineers working in this area. However, caution is needed, particularly for inexperienced novices, when applying FEA and its calculations.

Engineers Australia has published a new practice note addressing some common issues and potential pitfalls that can arise in the modelling of concrete building structures using such packages.

Written by practising structural engineer Tim Messer, the practice note takes the reader through a range of decisions users have to make when applying FEA during the design process. The issues covered include modelling inputs, deflection, modelling decisions, ultimate limit state design, forensic engineering and a checklist for validation of results.

It also has five case studies where inexpert use of FEA led to structural failures with dramatic consequences.

Titled “FEA in the design of reinforced concrete buildings – How to make the best use of FEA packages and avoid potential pitfalls”, the practice note is available through EA Books, a department of Engineers Media, a wholly owned subsidiary of Engineers Australia.
