I want to place a beam spanning 16' that will replace a wall

Customer Question

I want to place a beam spanning 16' that will replace a wall in the center of my single story truss roof. there is aprox. 13' on either side of the wall. about 6' of the 16' opening is currently open with no header of any type and no measured deflection of the truss at the ceiling. I was going to place a LVL beam 9.25"x4.5" across the larger opening for my piece of mind. I live near Atlanta, Ga so snow load is very negligible. the house is on a crawl space with a beam with block pillars that runs the length of the house.

Hello. How are you doing? I'll be happy to assist you.

Do you have real manufactured trusses with metal plates connecting the members?

Then it is almost certainly not a load bearing wall. Trusses almost always span between their ends without an intermediate support.

It has a double top plate and is built over the beam and supports in the crawl space. I just want to be safe.
Expert:  StructuralEng replied 1 year ago.

If you want to be safe and assume it's load bearing than you need a larger beam that what you're talking about.

do I need to go to an 11.5 x 4.5 beam?
Customer: replied 1 year ago.
I guess because I see no deflection in the trusses that are already not supported I thought that a beam would be for my peace of mind more than major structural support

It would be 5.25". LVL are 1.75" wide
