From what I can see, the IBC 2000 makes timber framing for other than residential structures very difficult, perhaps impossible if you have no shear walls. 1609.1.5 and 1614.5 requires that the lateral force resisting system shall meet the seismic detailing requirements of the code even when the wind effects are greater than the seismic effects. There are lots of new, complex seismic requirements even in areas that other codes say are not seismically active enough to worry about.
