Advisory Desk Notes

Advisory Desk or AD Notes reflect recent developments in technical standards or new knowledge that designers need to be made aware of. Some of them arise because a question is being frequently asked of the steel sector’s technical advisers. They have always been recognised as essential reading for all involved in the design of constructional steelwork. Published by the SCI in NSC magazine, they are brought together here for your reference.
