2018 Wood Frame Construction Manual

2018 WFCM
  • The 2018 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 has been approved by ANSI as an American National Standard. The 2018 WFCM is referenced in the 2018 International Building Code and 2018 International Residential Code.

    Tabulated engineered and prescriptive design provisions in WFCM Chapters 2 and 3, respectively are based on the following loads from ASCE/SEI 7-16 Minimum Design Loads and Associated Criteria for Buildings and Other Structures:

    • 0-70 psf ground snow loads
    • 90-195 mph 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.

2018 WFCM Workbook

2018 WFCM Workbook
  • Design of Wood Frame Buildings for High Wind, Snow, and Seismic Loads (2018 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, 2018 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.
