ICC ES evaluation reports can be obtained online at to use bearing charts:1. Determine the thickness required for the LP LVL beam and calculate the maximum Select the appropriate table for 1-ply (1-3/4"), 2-ply (3-1/2") or 3-ply (5-1/4").

Tabulated values are based on a support with minimum allowable bearing strength of 1020 psi. This is suitable for beams bearing on steel or the end grain of Make sure the support is structurally adequate to carry the reaction. Compressive strength parallel to grain of studs may require more studs than the bearing length above For beams bearing on wood plates, the required bearing length will increase based on the bearing strength (compression perpendicular to grain) of the species and grade used for the plate local code requirements concerning minimum values above are valid for the following LVL species.
