Glulam Floor System
Glulam Floor System
(OP)
I always see glulam's being used in roof systems but never for floor systems. It's a straightforward design in the NDS, but I'm not sure how the most efficient framing is typically laid out. Does anyone know of case studies for using glulams in a floor system? It will be an exposed structure from below.

Glulams are used both with wood decking and plywood with light weight concrete, for floor construction. Typically your beam spacings are 4' to 6'.
If you are using wood decking generally the most economical layout is one where you use 2" decking for both floor and roof construction. Although the use of 2" decking requires closer beam spacings generally that will cost less then a sytsem that uses 3" decking.

Also as you indicated I think a lot of engineers avoid wood design because they are not familiar with it or they don't like to do wood design. Architects however tend to like wood. Many time the people I work with have to talk an architect back into using wood when an engineer has talked them out of it.
