I have a 2 story wood framed building 175'x72' with interior steel framing supporting wood trusses. This is a spec building with no interior build-out at this time. Too many windows/doors to rely on exterior shear walls. I have moment frames parallel to the long face and braced framed parallel to the short face. Floor deck is 3/4" plywood with 1" gypcrete. Roof deck is 5/8" plywood. Any suggestions on deck properties and flexible or pseudo/flexible diaphragm?
