I am with MiketheEngineer, fire would be my greatest concern, as is for all types of buildings especially combustible material, that gives me the woollies…
Actually, steel loses its strength faster than large sections of timber char so sometimes the mental picture of wood burning is counterintuitive to the reality.
According to the paper it looks like the taller wood buildings (20-30 stories) still need steel floor beams tied to a structural (steel/concrete) core.
