The 2001 Edition is the current code-referenced version of the Wood Frame Construction Manual (WFCM) for One- and Two-Family Dwellings. The 2009 International Residential Code (IRC) contains an erroneous reference to the 2008 WFCM. ICC has acknowledged the error and will be correcting it in the next printing of the IRC. The next version of the WFCM is tentatively slated as the 2012 Edition to coincide with the 2012 IRC.
Design of Wood Frame Buildings for High Wind, Snow, and Seismic Loadings (WFCM Workbook) provides a design example, typical checklist, and background information related to design of a wood-frame structure in accordance with the Wood Frame Construction Manual (WFCM) for One- and Two- Family Dwellings, 2001 Edition. The design example uses plans from a 2-story residence as the basis for a structural design to resist wind, seismic and snow loads.
Special notice about changes to southern pine design values.
AWC has developed a new series of easy-to-use Guides to Wood Construction in High Wind Areas. Separate documents address wind design requirements in 90, 100, 110, 120, and 130 mph (Exposure B) wind zones (for other wind speeds and exposures see the 2001 WFCM). These Guides are based on provisions contained in AF&PA's 2001 WFCM, the reference document for high-wind wood-frame construction in the International Residential Code (IRC). Use of the high wind provisions of these Guides will result in design solutions that prescriptively meet the requirements of the WFCM and the IRC.
Errata and addendums that have been developed for AWC documents are available here in PDF format.
The Caribbean Basin Builders' Guide to Panelized Wood Construction in High Wind and Seismic Areas (Guide) is provided to simplify construction and design of wood frame buildings in areas where design wind velocity requirements do not exceed 150 miles per hour, mph (241 kilometers per hour, km/h) exposure category C and design seismic requirements do not exceed seismic design category D2. This Guide is also in compliance with the 2001 Wood Frame Construction Manual (WFCM) for One- and Two-Family Dwellings. The provisions of this Guide focus on ensuring structural integrity for resisting wind and seismic loads (not simultaneously). Additionally this Guide provides basic design provisions to resist floor and roof live loads. This Guide does not specifically address other loading conditions. These additional loading conditions must be considered as required by the building code and are addressed in the WFCM.
