Is the wall supporting a roof? Floor? What is the hoist length on each side of the wall? Is it supporting any ceramic tile?
Customer: replied 2 years ago.
I have been told the construction is a double queen truss on 24" centers The trusses are 2x4 and are 40ft long. The wall is in the center running perpendicular to the ceiling joist part of the truss Not sure what hoist length is so I would say yes to roof support

I am in Houston Tx and have not seen snow in 20 years

You can plan for a 7" x 20" 2.0E LVL to limit deflection to about 1/2"

Thank You; That sounds awful large I don't think I am explaining what I have good enough. All my construction books tell me I should be able to do this with 3 2x12s bolted together. I thought a laminated beam would be smaller and stronger.
How about if I decided to go with metal. Would it help if I sent you pictures.

Just wanted to say in case it made a difference this is Single story.
Expert:  StructuralEng replied 2 years ago.
Pictures will help. But a 20' span supporting a 20' tributary width is not even close to working with a triple 2x12. What construction book is telling you that will work?
