What size beam
Structural Engineer: StructuralEng, Consultant replied 3 months ago
I can size the I beam only for this question. What is the beam span? What is the joist length on each side? Will it support any ceramic tile?
Ask Your Own Structural Engineering Question
Customer reply replied 3 months ago
No tile and 35' long 6"wide
Customer reply replied 3 months ago
Do I need to put in casings in dirt crawl space and how far down do I dig for those
Structural Engineer: StructuralEng, Consultant replied 3 months ago
I can size the beam for what you want. If you want to clear span then I will size the beam for that. I will only provide one answer here. Beam size or how to do the posts. Not answer multiple questions in one thread
