How do you size a beam for a load bearing wall?

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.

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 2x8 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 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.

How thick of a beam do I need?

Design a beam depth based on the rule of thumb for estimating the depth of manufactured beams which is to divide the span by 20. Beam depths are typically 5 1/2 inches, 7 1/4 inches, 9 1/4 inches, 11 1/4 inches, 11 7/8 inches, 14 inches, 16 inches, 18 inches, and 20 inches.
