Would an 8x8 bolted to a 10x10 substitute for the 8x18 ?
Customer reply replied 11 months ago
Here is what I mean, please see attached. If this would work I could build the upper portion of the bend separate then bolt them to the lower section.
Structural Engineer: StructuralEng, Consultant replied 11 months ago
That's what I assumed. That is not the same as a 18" beam
