It is important to note however that the depth of a member is influenced not only by the span but by such variables as spacing loads support conditions deflections and clearance require. And the back span has to be at least twice the cantilever distance.

The total load on a rafter is given by w which is calculated using equation 1. The higher tonnage and airflow values correspond to buildings that are located in hotter more humid climates because the primarily load within these types of buildings will be due to the large.
