For roof members with slope (1/4)/12 or less final design must ensure that ponding instability
will not occur.
For roof members with slope (1/2)/12 or less final design must account for Rain -on -Snow
surcharge load.
Notes
Design meets Code minimum (L/180) Total load deflection criteria.
Design meets Code minimum (L/240) Live load deflection criteria.
Design meets arbitrary (1") Maximum Total load deflection criteria.
Calculations assume member is fully braced.
Design based on Dry Service Condition.
The analysis of solid sawn wood members is in accordance with the NDS and is limited to the
output shown above. All other support and design for these products, including but not
limited to notching, connections, installation, and engineer/architect certification is the
responsibility of the project's design professional of record.

Design does not consider perpendicular to grain stress on the sill plate or other supporting member.
Notes
Allowable loads are based on a minimum eccentricity of 0.167 multiplied by the column thickness or
width (worst case).
BC Calc does not perform shear wall or connection design for in -plane load transfer.
