Designing a Concrete metal pan deck suspended on I Beams. 1

[Stucco]

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?

You seem to have a handle on the design brief and your preferred materials and method of construction.

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.

...also, by the sound of your structural arrangement the connection between the 16" and 14" sections will be subject to bending moment and shear force. Have you stiffened the connection to ensure that the flange forces are adequately transferred between the 16" and 14" sections to achieve moment continuity in the beam?

looks like you are building your home like a hotel. The beams carry the load but are close in bending stress in the 36' section.

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