Listed are 46 tables based on common loading conditions for floor joists ceiling joists and rafters.
The tables permit a bearing length of up to 3 5 inches but since 1 5 is probably the worst case that you.

Load tables are calculated using section properties based on the steel design.
Simplified maximum span tables for selected visual and mechanical grades of southern pine lumber in sizes 2 4 thru 2 12.
Roof deck maximum spans.
Beam span maximums are based on a maximum anticipated live load.
Table 9 1 in span tables for joists and rafters figure 5 gives a required compression value of 237 psi for a span of 16 feet and bearing length of 1 5 inches.
Roof load limited by bending.
Two inch nominal thickness allowable roof load limited by deflection.
Building codes for residential decks only require 40 psf.
Fewer posts on upper level decks are typically more desirable to the occupants and this drives the use of larger framing materials for longer spans.
Three and four inch nominal thickness.
Loads shown in the shaded areas are governed by the live load deflection.
