I'm looking at Clause 27 of CSA Standard S16-01, I read that connections must be ductile. Can you elaborate? – J.M. 10/1/2004
That is a very good question, but harder to answer in a few words. Although steel is ductile, according to Michael Gilmor, the manner by which we attach members and components can vastly improve "ductility" of the assembly. One needs to avoid failures involving net section fracture or welds that are loaded transverse to the weld axis. Preferably failures that are on the gross section and welds that are oriented longitudinally will exhibit more ductile behaviour. This question appeared in the "Ask Dr. Sylvie" column of Advantage Steel no. 21, Fall 2004.
