seismic design of buildings
does anyone know how similar in content are the seismic provisions are for canada vs. u.s.a? mainly the national building code of canada 2005 vs the ubc or ibc.  
a question for practicing engineers:  how much more additional time do you feel you spend on designing buildings in a seismic active region compared to a non active region where say wind is usually the only governing lateral load?  i am junior engineer, and i just feel that the need to do seismic design and all the various different code and ductility requirements, seems to take quite a bit more time (perhaps it's because my relatively limited experience)  however, i quite enjoy doing it.
