Wrap around porch build. Beam on top or lagged? Many questions
I'm getting ready to submit plans to my city for a wraparound porch and have a few framing questions before I finalize the design.
The porch will be approximately **75 feet long by 10 feet wide**. My plan is to use **6x6 posts** supported by concrete sonotube footings. I'm located in **Minnesota**, so I'm also trying to determine the proper footing size and depth.
While looking at building plans and watching YouTube videos, I've noticed that many builders simply lag-bolt the beam directly to the side of the posts without notching the posts or providing a bearing surface for the beam. Is this an acceptable method, or should the beam be notched into the posts so it bears on the wood instead of relying only on the fasteners?
I'd also like the **same 6x6 posts to support both the deck and the porch roof**.
Here are my questions:
* What diameter sonotubes and footing depth are typically required in Minnesota? * Is it acceptable to lag-bolt the beam directly to the posts, or should the posts be notched to support the beam? * Can I frame the roof using only **2x6 top chords?** * What size floor joists would be appropriate for a 10-foot-wide porch with pressure-treated decking?
Any advice or recommendations would be greatly appreciated. Thanks!
