The article calls these "Smart steel columns". I guess they know better than to fracture at the wrong time. Sort of a Chuck Norris thing.
Seriously, I read the article but it's going to take more time than I have right now for me to study his ideas.

Subject: Smart Columns Article
Did anyone read the "Designing for horizontal movement" article in the Dec '08 issue of Structural Engineer magazine? The phrase "again reach full plastification" raised a flag for me. Are these columns intended to work by exceeding there elastic stress, and doing it more than once? Am I missing something?
