I want to make a flat roof covered parking area between two buildings. I have 3 heavy steel trusses 50' long and would like to attach 30-40 foot long sections of 18 or 20 gauge pan decking to create the simple 40ft x 50ft roof.
I got to thinking about how this would be a giant sail. Could get quite the lift in a wind storm. I was planning on splitting a 12 yard truck to do the footings, so 20,000+ lbs of concrete at each end of this tied into the monolithic building foundations at either end.
How do I design for the wind's potential to "lift" this roof?
