Plywood Diaphragm on Steel Framing
Plywood Diaphragm on Steel Framing
(OP)
Has anyone ever seen or designed a steel monoslope roof structure with wide flange rafters below wide flange purlins and braced using a plywood deck? I am working on a custom home and this is how the owner has detailed it out and I am not sure exactly where to go for the capacity (in lbs/ft) for the diaphragm.. Can anyone help?
