2012 Wood Frame Construction Manual

The 2012 Wood Frame Construction Manual (WFCM) for One- and Two-Family Dwellings was developed by the American Wood Council's (AWC) Wood Design Standards Committee and is referenced in the 2012 International Building Code and 2012 International Residential Code.

Tabulated engineered and prescriptive design provisions in WFCM Chapters 2 and 3, respectively are based on the following loads from ASCE 7-10 Minimum Design Loads for Buildings and Other Structures:

  • 0-70 psf ground snow loads
  • 110-195 mph 700-year return period 3-second gust basic wind speeds
  • Seismic Design Categories A-D
  • The WFCM includes design and construction provisions for connections, wall systems, floor systems, and roof systems. A range of structural elements are covered, including sawn lumber, structural glued laminated timber, wood structural sheathing, I-joists, and trusses.

     
     

    Non-member $​80.00
    Member/Student* $40.00

    * Qualified students are those who are full-time students enrolled in a wood design course at a university or college.

    Accompanying the WFCM is an extensive Commentary, which provides background information and example calculations for various sections and tables of the WFCM.

    WFCM Commentary only available with purchase.

     

    Design of Wood Frame Buildings for High Wind, Snow, and Seismic Loadings (2012 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, 2012 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.

     
    WFCM High Wind Guides

    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 115, 120, 130, 140, 150, and 160 mph (Exposures B and C) wind zones (for other wind speeds and exposures see the 2012 WFCM). These Guides are based on provisions contained in AWC's 2012 WFCM, the reference document for high-wind wood-frame construction in the 2012 International Residential Code (IRC) and 2012 International Building Code (IBC). Use of the high wind provisions of these Guides will result in design solutions that prescriptively meet the applicable requirements of the WFCM, IRC, and IBC.
