2X12 LVL BEAM SPAN TABLE CODE

The last option could get you in serious trouble, you may want to consider buying the specified beam. This span table excerpt shows two possible sizes of built-up floor beams (2 X 10 and 2 X 12). Either you get an engineer to approve your beam, you swap it out for the specified LVL beam, or you violate your permit. If he declines to allow you to use your beam, you have few options. My suggestion is that you discuss the issue with the inspector, with luck he will tell you exactly what you need to do to demonstrate that your beam is adequately strong. Below are some common beam span values from Table R507.5 of the 2018 IRC: 2×6 (double) Joist span of 6 feet allows a beam span of 6 feet 11inch, 18 feet requires 4 feet even 2×8. If you tie your 8 ft rafters together at just the one the sheathing joint (center of length of room or 8 ft from one end. To calculate beam span, you need to consider the wood species and grade, size of the beam, and the joist span. Moment sigmaZ, where Z is the section modulus width height2/6 for rectangular section. Pushed the limits of span charts to make the open floor concepts of today a reality. As the table shows, no 2×8’s meet the span and spacing requirements, but a 2×10 with an E of 1,300,000 psi and Fb of 1093 psi can span 15 feet 3 inches more than enough. That is a fairly simplistic way of looking at it.

A home made beam such as you describe is untested, and cannot readily be demonstrated to have a particular strength. Joist, LVL Microllam, LSL Timberstrand, and PSL Parallam. An LVL is an engineered structure, built in a controlled environment, and rigorously tested to make sure it supports the required load. I am not certain you understand the difference between a home made beam and an LVL. A 3-ply with 2 X 10s would mean that three 2 X 10s are. The user enters the member geometry, adds loads, holes and other relevant data and then selects a product for. It also shows the maximum that the beam can span for various numbers of such pieces of lumber built together (this is indicated by 3-ply, 4-ply and 5-ply). Joists and headers for doors are quite different, there are typically standard sizes for room types and spans in the code. This span table excerpt shows two possible sizes of built-up floor beams (2 X 10 and 2 X 12).

The only exception would be if there was a specific provision in the code that specified a particular size beam for a specific application, which is pretty unusual. My building inspector would never specify a beam, that would suggest he was accepting responsibility for the design, which he would not do.
