Hi,
Can anybody give some information about average of consumable steel (including rafters, purlins, roof and vertical bracings…) in common clear span rigid frames with built-in welded sections . (e.g. for Span: 50-60', bay and height: 20', roof slope:%15-20).
What are the results for truss included structures?
Thanks

(My results for rigid frames are about 6-7 lb per sqft for 30 lb/sqft snow load and in a high seismic zone.)
