2021 IRC header span Table

New girder/header tables have been revised to incorporate the use of #2 Southern Pine in lieu of #1 Southern Pine. New tables address alternative wood stud heights and the required number of full height studs in high wind areas. 2018 International Residential Code (IRC New girder/header tables have been revised to incorporate the use of #2 Southern Pine in lieu of #1 Southern Pine. New tables address alternative wood stud heights and the required number of full height studs in high wind areas. 2018 International Residential Code (IRC) Rafters shall be sized based on the rafter spans in Tables R802.4.1. Header Spans Girder and header spans are updated assuming No. 2 Southern Pine rather than No. 1 Southern Pine as used in the 2015 IRC. A footnote is added to clarify that headers and girders are assumed to be braced; for headers with pony walls above, a further reduction in span is taken for 2x8 and larger headers. Modification Table R602.7.5 Table Rim board header size, material and span shall be in accordance with Table R602.7(1). Rim board headers shall be constructed in accordance with Figure R602.7.2 and shall be supported at each end by full-height studs. The number of full-height studs at each end shall be not less than the number of studs displaced by half of the header span based.

The vertical and lateral load paths of conventional residential decks are addressed in the 2018 International Residential Code. Specific design guidance includes convenient span tables for joists and beams and charts of post sizing limitations and connection methods still referenced in 2018 IRC.

Relevant Tables and Figures ICC Digital Codes is the largest provider of model codes, custom codes and standards used worldwide to construct safe, sustainable, affordable and resilient structures While the 2018 IRC includes single-ply header options in the span tables, subsection R602.7.1 and figures R602.7 (1) and (2) (see illustrations, above) address special considerations for single-ply headers. These sections require that you install flat 2-by boards at the top and bottom of single-ply headers The allowable spans of girders and headers fabricated of dimension lumber shall not exceed the values set forth in Tables R602.7(1), R602.7(2) and R602.7(3).

In 2018, the IRC added new rows to this table, Table R602.7 (1), but that's just the headline. There is more to a header than just its ability to span an opening. It also has to transfer whatever loads it carries to the jack studs below.

In 2015 IRC they have a table for number studs needed Portal frame details within the IRC specify simple span headers, with a maximum finished opening width of 18'. These details are based on testing done by The Engineered Wood Association, that included only simple span headers.

Joist and Beam Span Tables The joist span tables that have long been in the IRC are not based on a wet-use environment or for incised, treated lumber, both conditions that reduce the maximum allowable spans.

(the tables permit a bearing length of up to 3.5 inches, but since 1.5 is probably the worst case that you'll encounter for joist or rafter bearing, it's a safe value.
