How much weight can a 2×8 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 2×8 @ 16″ oc and most preferbaly 2×10.

Which is stronger glulam or LVL?

In fact, each 2×10 will support 1,200 lbs.

Is LVL stronger than dimensional lumber?

LVL offers several advantages over typical milled lumber: Made in a factory under controlled specifications, it is stronger, straighter, and more uniform. Due to its composite nature, it is much less likely than conventional lumber to warp, twist, bow, or shrink.

How much weight can a 2×12 hold?

How do you size a load bearing beam?

The formula for the section modulus is beam width times beam depth squared divided by 6. A two 2-by-6 standard beam has actual dimensions of 1.5-by-5.5 inches which would give a section modulus of 1.5 x 5.5 x 5.5 / 6 = 7.6 which is not enough for this example. A 2-by-8 beam would be sufficient.

How much weight can a LVL beam hold?

Note: a single 2×6 will support 347 pounds per lineal foot of beam. Therefore, a double 2×6 carries 2 x 347 = 694 pounds per lineal foot. The required E-value does not change when you double the 2×6 because as you double the allowable load, you are doubling the thickness of the beam.
