Header Supporting Floor and Roof Calculator. Use the drop downs to select your roof load, floor load, house width, and material to calculate the appropriate size of TimberStrand or Parallam header.
Calculate the size needed for a beam, girder, or header made from No. 2 pine or LVL. Covers any span and every load with pin point accuracy. Double check yourself with these span charts. Works with evenly distributed loads only.
Use this door header size calculator to find the correct lumber size for your door header or determine the maximum length that a piece of lumber for a door header can span.
25 Οκτ 2024 · Use this wood beam span calculator to check a wood beam of a particular size and length to see if it can support a given uniform linear load by comparing its allowable and required bending and shear stress.
LVL span calculator. Calculate LVL beam span on the rule of thumb for estimating the span of LVL manufactured beam which is to multiply the depth in feet by figure 20, resulting figure is span of LVL beam. For example: An 12 inches deep an LVL beam can span up to 20 feet (12″÷12× 20= 20 foot).
Calculate the allowable span distance for your LVL beam based on the load requirements. Input the beam dimensions and load specifications to find out how far apart you can space your beams for optimal support.
When sizing beams and headers, you need to have sufficient moment capacity (Fb), sufficient shear capacity (Fv), sufficient stiffness (EI) to satisfy the live and total load deflection criteria
