Floor Beam Quick Reference Tables To use these charts: 1. Select the correct table for the beam application you need. 2. Choose the required beam span in the left column. 3. Select the span carried on the top line. 4. Read the beam size or choice of beam sizes from table. Example: A 14'-0" span beam carries 15'-0" simple span joists on each side.
The industry markets LVL beams and headers based on the MOE value (modulus of elasticity = E) which along with the size of the beam (moment of inertia = I) determines the stiffness (EI) of the beam. The stiffness of a beam determines how much deflection a beam will experience under a given load. Deflection is a performance criteria established by
