Q: Where can I find tables for UBs so I can select beams based on maximum deflections of cantilevers and simply supported beams?
A: The Australian Steel Institute produces a publication entitled Design Capacity Tables for Structural Steel that can assist. You can purchase a copy of the publication by going to www.steel.org.au/bookshop. Note that you’ll need advice from a suitably qualified structural engineer to interpret the information in this publication.
