Triple 2x12 beam span table
Table 9.1 in Span Tables for Joists and Rafters (Figure 5) gives a required compression value of 237 psi for a span of 16 feet and bearing length of 1.5 inches. (the tables permit a bearing length of up to 3.5 inches, but since 1.5 is probably the worst case that you’ll encounter for joist or rafter bearing, it’s a safe value.)The stringer is 18 ft long between landings. A 2x12 stringer with a 12" run and 7" rise results in only 5.5" of actual cross sectional depth, so for load carry capacity the stringer is really a 2x6. No resonable number of 2x6 wood members can span 18 ft and support 100 psf. Any ideas as how to support the stair treads for this load besides ...In the 2012 IRC and earlier versions, the header span table for exterior bearing walls was published in the middle of Chapter 5, “Floors”—not a logical place when you’re thinking about part of the wall framing. Earlier tables included only 2-ply, 3-ply, and 4-ply headers. A new table was added in the 2012 IRC for single-ply headers.

You merely look for the distance you need to span; match the load per foot of beam to the appropriate Fb(strength) and E(stiffness) values listed; and bang: you have a winner! Span tables are easy to use, but they have limitations. They don’t provide fine-tuned results. Most beam tables only list ...Table 9.1 in Span Tables for Joists and Rafters (Figure #5) gives a required compression value of 237 psi for a span of 16 feet and bearing length of 1.5 inches.

Here is a checklist of steps to follow when using span tables. Check plans to determine span and on-center spacing (design conditions) Check codes for allowable live load, snow load, dead load and deflection; Select …Since the 26-ft.-wide building is 6 ft. wider than the 20-ft. width from the table, calculate the following: 0.75 in. per ft. × 6 ft. = 4.5 in. Subtract the above number from the header span for a 20-ft.-wide building to find the allowable header span for a 26-ft.-wide building: 3 ft. 11 in. – 4.5 in. = 3 ft. 6.5 in. Canadian Span Book 2020 (updated September 2021) WebStore.

Erratas Canadian Span Book 2020 (updated February 2021) Canadian Span Book 2020 (updated September 2021) For other bearing lengths, use the Allowable Floor Load Tables (Tables 21-26). Steps in Using Table 13: 1. Verify the applicability of this table’s loading conditions and load duration factor. 2. Find the span of supported floor framing (i.e., sum of the spans of the joists or trusses that frame into the beam) that equals or exceeds the intendedA) A Wider Building/Room has longer joists and supports more weight above it, so the Span Decreases (or a bigger beam is needed) as you go from a 28 Wide Building to a 36 Wide Building. Similarly, while it is not shown in these tables, if the Building/Room were only 15 or 10 feet wide, the span would increase or a smaller beam would be needed.
Conclusion. The distance an LVL beam can span depends on a plethora of factors. Some manufacturers limit their beams to 60’ due to transportation issues, while others have the capability to manufacture beams up to 80’ long. So, the longest unsupported span possible using LVL would be 80-feet.The user enters the member geometry, adds loads, holes and other relevant data and then selects a product for analysis.
