Another deck beam span question


...you proably can move them out, what I'm saying is you will most likely need an engineer to sign off on it.

Roof pitch 2 1/2:12 and covered with steel standing seam.

Another deck beam span question


Does anybody see anything wrong with this table? Using SYP 2x12s @ 16 O.C., I can span 18 feet....with or without overhang? Is this comparable to what others show?

Thanks!

If you are asking these types of questions on the internet and people keep telling you to get an engineer, I am surprised you have not been to one yet. Also did the IRC say it was a 32" footing for your soil type and your load for the footing? I would say get and engineer.

Another deck beam span question


I am an engineer, but of the electrical type.......state licensed and everything. However, I have asked several of my civil and mechanical engineer friends, but they know less about this than I do.........I know, I know.. I was surprised too. So, quit telling me to find an engineer. I'd rather talk to someone who has built more than one deck with a covered roof and I'd listen more to him than a moron engineer!

So you are figuring out what type of engineer you need to consult?? Here is a hint "STRUCTURAL" Big difference

I haven't seen too many schools that have a Structural Engineering degree. What would that be...... a BSSE? I think most Structural Engineers have a BSCE (BS in Civil Engineering). As I said before, one of my engineer friends is a Structural Engineer (BSCE), but does not work with wood...only steel (as in 7 story buildings).

I'm guessing by your post number that you may have more experience. So, what is the load on a 2' cantilever that is 20' long with 6"x6" roof posts supporting a 1/12 pitch roof w/o a ceiling using metal roofing?

Do you remember the formulas?
T = F * d, where
T = Torque F = Force (here, the force applied perpendicular to the axis)
d = Distance

Remember your lateral bracing to prevent sidesway.

Your project, as I stated a long time ago, is outside the space covered by the IRC deck guide. This is because you have loads NOT CONTEMPLATED in the Prescriptive Deck Guide. This does not mean you can't build it, and it does not necessarily mean you have to hire an engineer to design it, but someone needs to design it, unless you plan to size the structural elements by revealed truth from God. And since you think engineers are morons, and you claim to know more than your structural engineer buddy, perhaps you should size the pieces yourself, figure out how to put them together, draw up the plans, take them to the building inspector, and get them approved. Or just build it with no plans and no permit, why not?

As for getting someone on here to design the job for you gratis, would you also like someone on here to show up at your house and build it too? No charge?
