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.
Design values for structural lumber, structural glued laminated glulam timber, and fasteners were incorporated in the integral Supplement of the WFCM. Understand the purpose of the WFCM and its development process.
There are several design tools and standards to assist engineers, architects, and building officials with the design of shear walls. Reference to connector products available in the marketplace will be made without identifying particular manufacturers. For fastener design values, the NDS is the reference standard.
The WFCM prescriptive method will is used to illustrate the magnitude and applied location for loads applicable to low-rise wood frame construction. Expand all Collapse all. The Wood Frame Construction Manual WFCM will be used as the basis wccm loads and load paths that must be determined in design of low-rise wood frame construction. Walls sheathed with wood structural panels can be used to resist uplift alone, or simultaneously resist uplift and shear from wind forces.
We recommend users of early versions of Internet Explorer to update to Version 10 or later. He may be reached at bshowalter awc. In addition, this presentation will provide an overview of the significant changes in the WFCM relative to the previous edition.
WFCM Commentary only available with purchase. Shear wall story offset limits. Provisions contained in this document that are not included in the IRC are considered good practice recommendations.
Wood Frame Construction Manual –
This article originally appeared in the Winter issue of Wood Design Focus published by the Forest Products Society and is reprinted with permission. 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: Chapter 3 provides several prescriptive solutions derived from Chapter 2 load requirements.
Shear Wall Design Examples Several design tools and standards to assist engineers, architects, and building officials with the design of shear walls are available.
Capacities are based on provisions in the NDS and have been verified by full scale testing. Eng and Loren Ross, P.
2012 Wood Frame Construction Manual for One- and Two-Family Dwellings & Commentary to the WFCM
Be able to analyze format and content within the WFCM. Part 1 will provide an overview of appropriate loads to apply to residential structures and work through the roof story design.
The WFCM represents the state-of-the-art for design of one- and two-family dwellings for high wind, high seismic, and high snow loads.
Frank Woeste ator e-mail: These details have been derived from typical code provisions and are included in Chapter 2 for the convenience of the designer. Be familiar with specific provisions of the building codes referencing the WFCM. 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. Distribution of the PDF wfc, not permitted.
Attendees will learn the appropriate high wind, seismic, and snow loads to apply to residential structures based on code-referenced load standards. The WFCM includes design and construction provisions for high wind, seismic, and snow loads for connections, wall systems, floor systems, and roof systems.
Learn about the engineering basis of prescriptive tables wfvm to size wood members and connections to resist high wind, seismic, and snow loads in the roof story system.
An integral Appendix of the WFCM still contains 212 strap and ridge strap capacity tables for those wishing to maintain that option. This unit will provide a chapter by chapter overview of the WFCM which includes provisions for designing wood frame structures for wind, snow, and seismic loads.
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. Be familiar with the design approaches and referenced standards in the WFCM. Its reference in the IBC and IRC will allow for its use in those jurisdictions adopting the latest building code. Learn to use prescriptive tables to size wood members and connections to resist high wind, seismic, and snow loads in the roof story system.
The design example uses plans from a 2-story residence as the basis for a structural design to resist wind, seismic and snow loads. The local authority having jurisdiction should be consulted to determine whether conversion to a mph basis is permissible.
