For 12' Roof Panel + 2' Overhang; Load Width = LW = 12'/2 + 2' O.H. = 8'; Enter table on left at 8' read allowable span under required load; Thus for 100 M.P.H. wind Ioadlllve load or 1~d Width = 8'-0" Maximum Beam Span for 2" x 4" x 0.038" x 0,100" = __ Spans do not include length of knee brace. Add horizontal 'engt~ of knee brace to above spans for total beam spans. -Note: For small covers 2" X 2" beams may be used. (see table 3.1.1 for spans) Lawrence E. Bennett, P.E. CIVIL ENGINEER.
