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 loadllive load or 1.Fl. and load Width = 8'.0" Maximum Beam Span for 2" x 4" x 0.038" x 0.100" = .~~ .,. Spans do not indude length of knee brace. Add horizonlallenglh of knee brace to above spans for total beam spans ""Note: For small covers 2" X 2" beams may be used.
