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.

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?
