If you were payed to do so, or at least asked about- how would 1,500 foot tall rigid steal frame supper tall design compare in regards to steel usage? Roughly speaking, what is the optimal column spacing from a strength, stiffness and sway perspective?
233x233 feet wide at the base. Typically a building of this size is constructed as a core and tube or segmented tubes to maximize space and steel savings. I apologies about making such an odd inquiry.
