I mean data for single high-rises and their steel tonnage in kg/m² floor area subject to their height.
I have seen one diagram in a book about Fazlur Khan, but never came across another statistic about steel tonnages (for example for Sears Tower, J.Hancock Tower or others)...
i duno allot of that info is published its just matter of finding it perhaps wiki has the info on some building also if u find out who built said building they might be able to tell u two
