PLIB has updated Simplified Span Tables for Light Frame Construction, a previous WCLIB publication that had last been updated in the early 2000’s and had been out of print for several years.  The newly revised updated publication focuses on imported species and provides spans for floor and ceiling joists and rafters for a variety of common load conditions.

Simplified Span Tables for Light Frame Construction: Imported Species provides technical support to PLIB’s European members and non-members alike as well as to builders, code officials, engineers and retailers who use imported species. The publication is available as a free download from the PLIB website.

Species independent joist and rafter span tables can be found in the American Wood Council’s Span Tables for Joists and Rafters publication.
