What exactly is your question with respect to these trusses?
Customer: replied 6 months ago.
how they are facricated as i want to build them myself-- have full millwork factory and just wanting confirmation on loads on fabrication. Interior of beam would be 2--2x6 #1 yellow pine lam stock glued and screwed--two bottom cord-- two top cord --stiffiner every 24" plus diagional bracing as in truss -- 3/4 c-d ply exterior glued and screwed every 3 inch as per APA specs
Expert:  StructuralEng replied 6 months ago.
These appear to be plywood box beams, not trusses.
Customer: replied 6 months ago.
have inquired about visiting eagle span plant with no as an answer as he says his truss is proprietary in nature and will not reveal the construction--its not rocket science-just wood beams as in long span plywood box beam construction
Expert:  StructuralEng replied 6 months ago.
Of course they don't want to reveal construction methods. I could design a very specific case for you (single span length and loading condition) as an additional service, if you would like. I would provide the lumber layout, plywood requirements, depth, nailing pattern with a couple sketches.

there will be a second floor apartment -- downstairs for parking plus utility storage- upstair living on conventional foundation as well
Expert:  StructuralEng replied 6 months ago.
What exactly do you want? The entire frame or the box beam supporting the roof only?
Customer: replied 6 months ago.
The entire frame -- 48" centers
Expert:  StructuralEng replied 6 months ago.
I will submit an additional service offer for you for this. It will take a solid week or so to complete.
Customer: replied 6 months ago.
Forget it-- you have been no help at all-- it was a waste of time and money
