I am guessing some of this delay springs from the Loma Prieta Earthquake (1989).
Lots of structural retrofit there.
Yet I also guess that lessons from big quakes have been a part of the IBC review process. For decades.

- Gibbon1 7y agoYeah every time there is an earthquake they learn how new modern materials and construction techniques fail and perform worse than the previous ones. Kinda of like how joints in steel frame buildings held together with stupid janky rivets would shift and creek during earthquakes while strong modern welded ones wouldn't . Progress! No wait that last bit is bad. The steel at the welded joint buckles unless carefully designed. Which they weren't for the first 30-40 years.
