Any other thoughts? > the tag seems OK for what you intend to tag, one remaining problem could be verifiability. Are there objective criteria, e.g. who defines the cutoff where a building is still deemed sufficiently stiff, and when is it not? In some building law, the required stiffness will depend on the risk zone for earthquakes. Will the application of this tag depend on the jurisdiction? Will we have to retag all buildings if the definitions change? Will we be able to survey this, or does it require structural documentation and the knowledge to evaluate it? Cheers, Martin
