Car Port post load calculation
Good day everyone.
I have built a car port post in an inverted L shape and want to calculate the load that it can support. I think I have “over-killed” the posts enough. I am curious to see how much weight this structure could hold. Any way of calculating the load at the area which support the wood beam ? All metal is 1/4" thick. Base mounting bolts/rod is 5/8" All joints are welded with arc-welding @ 7018 @ 1/8" rod. Concrete base 12" sonotube with 24" footing @ 8" thick. Embedded re-bar 2 part setup . See attached pictures. Thanks, Ben |

Where I live - in Canada, Sonotubes are not a good thing. Water seeps down, freezes in the winter and then pushes the concrete straight up the smooth inside of the Sonotube. And we gotta go down 36" - 48". (Just finished building my own carport.) http://davesbrain.livejournal.com/2011/11/05/ |

Car Port post load calculation
Thanks for the reply Dave, I live near Ottawa, Canada.
I have poured a 24" diameter footing @ 5ft deep then poured the sonotube on top of it with rebar joining the concrete footing and sonotube. Code require 4ft deep, I have 5ft, it should be good. Sonotube without "base/footings" if not deep enough will be moved out of the soil from freeze and thaw. (i.e. most people do the sonotubes for fences and dig only 24", 2 years after the fence is out of alignment). Cheers! Ben |

Jesoosi Chistoosi - are those four inch square steel tubes? You could park a second car up there!

Almost ... 3.5" tubing @ 1/4" in thick.
I know, it's overkill haha, but I would really like to see how much it can support. A car... or a dump truck ? haha. |
