General Notes for Joist, Beam,
or Header Load Table
■
Table is based on:
– M-12, Southern pine design values (see page 2)
– Deflection criteria of L/240 total load, L/360
live load, and 100% duration of load
■
Allowable loads shown are the maximum uniform
loads (plf) that can be applied to the beam in
addition to its own weight, provided that the
minimum end-bearing requirements are met.
■
Beams and girders must bear on load-bearing
walls, piles, or concrete or masonry foundations.
For framing instructions, including
recommended fastening schedules, please refer
to the AWC Wood Frame Construction Manual or
your applicable building code.
General Notes for Floor, Rafter,
and Ceiling Span Tables
■
Table is based on M-12, Southern pine design
values (see page 2).
■
Maximum available length is 20'.
■
Joists must bear directly on beams, girders,
ledgers, or load bearing walls; or be supported
by hangers or framing anchors.
■
Spans shown are horizontal clear distances
between supports, and assume uniformly loaded
joists only.
■
Minimum bearing: 1½" on wood or steel, 3"
on masonry. Bearing across full joist width is
required.
■
Provide lateral restraint at the end of each joist
by fastening to a rim, band joist, header, or
other member or by using full-height blocking
between floor joist ends.
