(You should check this, of course, against your local codes.) My primary concern with 2x12s at 16 in. o. c. is not their load capacity but their deflection and vibration behavior.

Typically for a 26 foot span, size of LVL (Laminated veneer lumber) beam need to be 14-16 inches deep and 6 inches wide. So you would need something like a 5 1/4″× 14″ or 5-1/4×16″ LVL or engineered wood to span upto 26 feet used for residential application on normal weight condition.Lvl is an excellent choice in lumber for quality home building due to its strength and straightness. LVL beams come up to 60 feet long and are stronger than traditional sawn lumber beams. It is relatively easy to produce, and a few manufacturers in the U.S. keep the price relatively low for engineered lumber.Allowable deflection is generally expressed as a fraction of the span. A larger number in the bottom of the fraction represents a more stringent limitation. For example, the allowable deflection of a 12 ft span floor joist with plaster (L/360) is 0.4 inches (12 ft divided by 360). If that same joist had gypsum ceiling (L/240), the allowable ...LVL beam sizes start at 24 feet to 44 feet long and can go up to 60 feet. The LVL beam thickness is usually between 1.75 and 7 inches. The price for beams that fit 10 feet of space will range from $3 to $5 per linear foot , while a 20-feet span will need a beam that costs $6 to $11 per linear foot .To span 10 feet, you might consider using an LVL beam of approximately 3.5 inches in width and varying depths depending on the load requirements. A 3.5 x 9.25 inches LVL beam, for instance, could potentially span 10 feet under specific load conditions, but it's crucial to confirm this with load tables or a structural engineer.Second, all banding should be inspected prior to hoisting to make sure it is intact and secure. Again, never use the banding to lift the bundles. For trusses between 45-60 feet in length, at least two pick points should be used to lift a bundle (see Photo B1-12). For trusses over 60 feet in length, a minimum of three pick points should be used.If beam spanning is 30 feet in length, then their depth = (30 × 12) ÷ 20 = 18 inches, rounding it to 18 inches and width is 18/3 = 6″, thus you would need 5 1/2″ × 18″ size of Glulam beam for 30 foot span.

Engineer 10 adds that a No. 2 2×6 over a 16-ft. span can carry 10 psf while a 2×8 will carry 20 psf. Sistering the two together means a load-carrying capacity of 30 psf. “This is based on bending strength only not deflection, therefore a load larger than that will cause collapse,” he writes.(span/360) for a 30! span is 1" of deflection. L/240 would be 11⁄2," and L/180 would be 2" of deflection. Consideration might also be given to cases in which a joist with a long span parallels a short span or a foundation end wall. For example, a 30! span with up to 1" of allow-able live load deflection could be adjacent to an end wall with noWood roof trusses to span anywhere from 30 to 60 feet (and even more, with specialized designs) can now be bought from lumber yards at prices between $1 and $2 per lineal foot. That’s pretty good, considering that old-style 30-foot roof beams are hard to come by these days and, if available, cost more than one can afford and weigh more than ...Even if you're not great with spatial relations.
