Notes and Disclaimers
Loading Condition:
Calculated beam is assumed to be simply supported and subjected to uniform loading along its length.
Lateral Support
The top of the beam,joist,or rafter is assumed to be supported throughout its length(through attachment to floor or roof sheathing)to prevent lateral displacement,and the ends,at points of bearing,
have lateral support to prevent rotation.
Disclaimer
While every effort has been made to insure the accuracy of the information presented,and special effort has been made to assure that the information reflects the state-of-the-art,neither the American
Wood Council nor its members assume any responsibility for any particular design prepared from this Span Calculator.Those using this Span Calculator assume all liability from its use.
