If there is no strong wind, a 2x4 measuring at least 8 feet can support at least 1,000 pounds vertically.

How much weight can a 2x4 stud hold?

Depending on the length of wall, a 2x4 wall could support 20,000–30,000lbs. This wall would obviously contain a lot of studs, but that is still a ton of weight.

Are two 2x4 stronger than one 4x4?

Granted 4x4s when used vertically are still rather strong for most applications, but should never be used horizontally for something structural. Also remember and remind yourself (repeatedly, if need be ) that two 2x4 is NOT dimensionally the same as a 4x4. In this case, two 2x does NOT equal a 4x.

Can I use 2x4 for floor joists?

before being supported by a girder - then yeah, a 2x4 should be okay. 2x4 are suitable for ceiling joists where the LL is like 20 Lbs. If you got a good species with the highest Modulus of Elasticity and Best grade and use like 12" o.c. - you might get 8'' span.

How much weight can a 2x8 joist hold?

some of it gets pretty technical in nature, and mostly relates to pounds / square foot of loading. 2x6s are generally used for ceiling joists, esp since you said 24" oc and reallllly short spans only (5 or 6 feet ). Most floor loads would be a minimum of 2x8 @ 16" oc and most preferbaly 2x10.

How Far Can 3/4 inch plywood span?

Plywood panels over 3/4 inch in thickness are usually special order products. Thinner sheets of plywood can be glued together (laminated) to make a thicker panel for cutting sturdier shelves. The longest recommended span between wall supports for 3/4-inch-thick plywood shelves is 36 inches.

How much weight can a 6 by 6 post hold?

Most decks are built to a 50 pounds per square feet, and high capacity decks are built to 70 psf. That puts you at eiter 9250 pounds or 12950 pounds with 185 sq feet. These should be the numbers you base the amount of posts on. Now the maximum load of a 6x6 will depend on the coice of lumber.

How big of a beam do I need to span 20 feet?

Re: 20 foot clearspan beam size
In that case, you need something like a 12-16" GLULAM or LVL to span the 20' and can use simple 2x8-10 dimensional lumber 16"OC as floor joists.

You'd need some maths to figure out specifics but those 2x12's would hold around 150 pounds per foot x length x spans but then at some point you get into mode of rupture or elastics, dead weight live weight.
