Wind Sill Member Design

When NBCC is selected for the Building Code in the Job Settings tab, the Wind Sill member type becomes available under Wall members. The Wind Sill member is the lateral load resistance member(s) within an opening assembly. This member type does not typically support vertical loads for the opening assembly and is expected to be fully braced to resist buckling against lateral loads. Self-weight is not considered in the design of this member type.

The Member Type on the Report will display as "Wind Sill." Users will not be limited to a single ply when in Plank orientation. Typically the Wind Sill will only be analyzed for lateral loads, the vertical components of the member analysis are inconsequential.
