Designing a Concrete metal pan deck suspended on I Beams.
(OP)
I am building a house that has a walkout basement 36' across and 70' long. I have 45' I-beams 16" 40lb. spanning the basement so 9' cantilever's over the edge. I have welded a piece of 14" I-beam 4' to make a total of 13' from the house. I plan on drilling a hole for a footer to put an ajustable post (like a basement pole) under the end of each beam. These beams are on average 11' 8" apart. I plan on putting 4" Cee's on 16" centers across the beams and then install a 26 guage Industrial metal pan ontop of the 4" Cee purlins. Then build a retaining wall lip on the outside edge to hold a pour of 4" of concrete at the edge with 5" at the house so we have a slight slope to shed the water away from the house. I had planned on using welded wire cattle panels as my reinforcing. My question is reading some of the other posts on this site, is this enough support for a 5.5 sack concrete mix, which I was told would weigh around 3700lbs a square yard. My caculations this deck should weight around 34,000 lbs total in just concrete.
So should the structure I am planning support this? or do you have some suggestions?

However if you don't have the technical expertise to complete the design/check of this structural system then I suggest, with respect, that you engage a Professional Engineer who does.
With your design brief above, some reference drawings/sketches and perhaps an inspection this will be a relatively simple task for a suitably experienced Structural Engineer.

I dont have experience to comment on perlin design. Typically i use a 1/8"/ft min slope for exposed porches.
