Collar tie in a concrete roof

| I have a concrete roof (40X20) where my client wants a vaulted
ceiling. The ridge line is aprallel to the 40 ft. line Ridge beam has
to span almost 40 feet. (no middle posts required). There is a 3 ft
space between the ceiling and the roof. I'm thinking of using collar
ties above the ceiling line. I will design it to carry a tensile force
equal to the thrust.

Are you an engineer? If not, then this type of design is not for the
inexperienced.

| The 40 ft. span is the problem of course, probably need to design a flitch
beam or use an I-beam.
Bob's right about this, it's a situation where "if you have to ask....."
