2x6 Floor Support Ratings

Is the floor sitting on the ground or are you raising it up.

2x6 floor support ratings.

With an evenly distributed live load of 30 psf which the tables show the floor is able to support the total weight on the floor would be about 3 360 pounds. This is what we have done with our coup and our shed was built that way as well. 1 psf lb f ft 2 47 88 n m 2. For example a floor joist at 16 spacing s that can carry 53 pounds per linear foot would translate into a 318 pound single point load at its center.

I would go for 2x6 if the center of the joists won t be near the ground or on it. Maximum floor joist span for no. Fewer posts on upper level decks are typically more desirable to the occupants and this drives the use of larger framing materials for longer spans. A uniform load rating on a beam can easily be translated into what an equivalent maximum point load can be.

The species of lumber size of lumber and the load it carries. For conventional guardrail post installation bolted to the side of the framing larger framing will provide more strength in the rails. For upper level decks 2x10 is recommended as the minimum size to use for strong guard post connections. 2 grade of douglas fir are indicated below.

Live load is weight of furniture wind snow and more. The wooden joists or beams over your garage help hold your roof in place. It is a wierd connection the metal plates are on the 2 sides of the 2x6 top and bottom and the bolt is about 7 long through the end of the 2x6 s. 1 ft 0 3048 m.

The extra two inches of vertical distance when a floor is framed with 2 x 10 joists rather than 2 x 12s can be quite important for example. 2x6 joists should only be used on ground level decks that do not require and will not provide for any guards. Dead load weight of structure and fixed loads 10 lbs ft 2. If it is sitting on the ground then you can go ahead and use 2x4s.

I can check the metal plates for bearing and tension and the net section of the 2x6 for tension and the bolt for shear. Save yourself a lot of money that way. Common sense tells you that large floor joists can carry more load and spacing joists closer together also increases the load bearing capacity of a floor. The span of a beam is dependent on a few variables.

If you have an attic over your garage these joists also bear the load of your attic flooring and any materials you store in the attic. Increasing the total weight on the floor to 4 480 pounds however results in a live load of 40 psf which is beyond the floor s load capacity.
