For Sloping Rafters The Span Is Measured Along The Horizontal Projection.

Web this publication provides simple span tables for selected grades of southern pine lumber joists and rafters under a variety of load conditions. Web spfa has created 46 simplified maximum span tables based on common load conditions for floor joists, ceiling joists, and rafters for selected visual and mechanical grades of southern pine lumber in sizes 2×4 thru 2×12. Web span charts for deck joists and beams in a variety of framing materials, including wood and steel. Web tabulated spans are the distance from face to face of supports.

Web This Table Is Based On The Use Of Ponderosa Pine No.

Let’s start by taking a broad view. Web a complete analysis of wood’s mechanical properties is complex, but understanding a few basics of lumber strength will allow you to size joists and rafters with the use of span tables. The commentary provides further information on span measurements including a chart which converts horizontal distances to sloping distances, or vice versa. The table accounts for wet service conditions and an incised lumber reduction for species commonly incised for pressure treatment penetration.
