The Wood Frame Construction Manual (WFCM) for One- and Two-Family Dwellings was updated and is designated ANSI/AWC WFCM (Figure 1). WFCM. • Wood Frame Construction Manual. • WFCM uses ASCE 7- 10 wind design provisions. • IRC uses ASCE wind design provisions. The Wood Frame Construction Manual (WFCM) for One- and Two-Family Dwellings was developed by the American Wood Council (AWC) Wood Design.

Part 2 will deal with design of wall and floor systems, including shear wall design and appropriate connections between roof, floor, wall, and foundations to maintain load path. These details have been derived from typical code provisions and are included in Chapter 2 for the convenience of the designer. This webinar will be a continuation of the Loads webinar and use the loads developed previously to illustrate the importance of load path continuity in buildings. Permanent Bracing for Residential Metal-Plate-Connected Wood Trusses In wffcm unit, the basics of permanent bracing design for wood trusses and the importance of a complete bracing system will be presented.

For a volume license the PDF is wfc, to the person in which it is assigned. There are separate wind speed maps for each Risk Category in the code, and Exposure D will become applicable again in hurricane prone regions.

Note that Chapter 2 also contains some necessary construction details. In ArticlesCode Updates Comments 0.

Using plans from a 2-story residence, participants prescriptively design the structure to resist high wind, seismic, and typical residential gravity loads. This course will outline several resources available for shear wall design and compare design results. Be familiar with the significant changes between the and WFCM. A range of structural elements are covered, including sawn lumber, structural glued laminated timber, wood structural sheathing, I-joists, and trusses.

The Wfvm includes general information on loads and resistances.

Attendees will learn about the engineering basis of prescriptive tables used to size wood members and connections to resist high wind, seismic, and snow loads in the wall and floor systems. Design properties for horizontal diaphragms and shear wfcj were incorporated in the integral Supplement of the WFCM.


This option is mobile friendly and compatible with all devices, including mobile tablets and smart phones. Expand all Collapse all. There are several design tools and standards to assist engineers, architects, and building officials with the design of shear walls. Learn to use checklists and detailing summaries to ensure a complete load path is prescriptively designed for the roof story.

More Wood Construction Short Courses. Ground snow loads in the WFCM take into account both balanced and unbalanced snow load conditions.

Be able to describe how loads are distributed to buildings both vertically and horizontally Be able to describe several different load paths that are critical to improved building performance during high winds Be able to recognize structural configurations or significant loading in building framing that might present construction challenges to framing continuous load paths Be able to recognize construction defects that could potentially fail under high wind loads Equivalencies: The latter tends to provide more conservative results.

Therefore, it is perfectly acceptable to use Chapter 3 provisions for parts of a design and Chapter 2 for other parts. The design example uses plans from a 2-story residence as the basis for a structural design to resist high wind, seismic, and snow loads. A range of structural elements are included such as sawn lumber, structural glued laminated timber, wood structural panel sheathing, I-joists, and trusses.

Research: Rating Action: Moody’s Affirms 11 Classes of WFCM LC5 – Moody’s

Specifying and Constructing Floors to Accommodate Ceramic Tile and Stone The use of brittle floor covering materials requires 20122 planning and coordination at the 2021 design phase. The local authority having jurisdiction should be consulted to determine whether conversion to a mph basis is permissible. Prescriptive details for commonly required lateral and diagonal bracing needed wcm meet the assumptions of the truss design drawings for residential applications will be reviewed.


The WFCM includes design and construction provisions for connections, wall systems, floor systems, and roof systems. Learn to use prescriptive tables to size wood members and connections to resist high wind, seismic, and snow loads in the roof story system.

Vertical and lateral load paths will be described including the role of shear walls in buildings.

Frank Woeste ator e-mail: For fastener design values, the NDS is the reference standard. This unit will provide an overview of the significant wfck to the DCA 6 and include several examples showing application of the guide. Leave a Comment Click here to cancel reply. First Name Last Name.

2012 Wood Frame Construction Manual for One- and Two-Family Dwellings & Commentary to the WFCM

New risk-based maps generally reduce areas of highest seismic risk along the New Madrid fault and in the Charleston, SC area. The PDF Download is licensed per individual in which the individual can place on up to four electronic devices for their personal use. The Wood Frame Construction Manual WFCM will be used as the basis for loads and load paths that must be determined in design of low-rise wood frame construction. Understand the difference between segmented and perforated shear wall design.

Walls sheathed with wood structural panels can be used to resist uplift alone, or simultaneously resist uplift and shear from wind forces.
