AB - The span-to-effective-depth method (L/d method) is a very popular way of verifying the of limit state of deformation, which is often critical to commercial viability in commercial structures. Yet there have been many comments in the UK relating to the soundness of the L/d method given in Section 7.4.2 of Eurocode 2 (EN 1992-1-1) and repeated in Section 7.6.5.2.4 of Model Code 2010. This paper describes how background work has informed interpretation of the rigorous method of determining deflection to allow a spreadsheet to be written and be used to generate data, which were compared to data for the current L/d method and for a proposed modification of the current L/d method. However correlation of the methods is not good. Further work is considered necessary in order to address discrepancies and provide a practical method of verifying the limit state of deflection with greater confidence.
