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.

Suppliers of building products used in the residential construction and their wfcj staff may benefit as well by enhancing their knowledge of a code-conforming whole building design. The WFCM includes design and construction provisions for high wind, seismic, and snow loads for connections, wall systems, floor systems, and roof systems.
This webinar builds on the three previous Load, Load Path, and Connections webinars to describe how loads must be transferred through the building to reach the foundation system. The primary characteristic of this method is increased nailing of panels to framing to provide a continuous load path and enable uplift loads to be transferred to existing wall anchorage at the foundation. Distribution of the PDF is not permitted.
The latter tends to provide more conservative results. Due to minimal design information on elevated foundations in the building code, this webinar is intended to provide some design basics that may not be readily available.
Understand hold down design. More Wood Construction Short Courses. These details have been derived from typical code provisions and are included in Wccm 2 for the convenience of the designer. 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 roof story system.
Wood Frame Construction Manual –
The local authority having jurisdiction should be consulted to determine whether conversion to a mph basis is permissible. For a volume license the PDF is licensed to the person in which it is assigned. Reference to connector products available in the marketplace will be made without identifying particular manufacturers. Shear wall story offset provisions were clarified in the WFCM.
Learn to use checklists and detailing summaries to ensure a complete load path is prescriptively designed for the roof story.
In 20112 to improve in-service performance of the tile or stone covering, details for the installation of span-rated wood-structural underlayment for a two-layer wood substrate system will be presented. Be familiar with the significant changes between the and WFCM.
Attendees will learn to use prescriptive tables to size wood members and connections to resist high wind, seismic, and snow loads in the wall and floor systems. Provisions dfcm in this document that are not included in the IRC are considered good practice recommendations. Wind speeds are higher, but load factors for design are also adjusted so that the net effect will be a reduction of wind pressures in some regions Line Design properties for horizontal 212 and shear walls were incorporated in the integral Supplement of the WFCM.
Attendees will learn the appropriate high wind, seismic, and snow loads to apply to residential structures based on code-referenced load standards. There are several design tools and standards to assist engineers, architects, and building officials with the design of shear walls. Wffm WFCM includes general information on loads and resistances.
STRUCTURE magazine | WFCM Changes
This unit will provide an overview of the significant changes to the DCA 6 and include several examples showing application of the guide. Separate documents address wind design requirements in,and mph Exposures B and C wind zones for other wind speeds and exposures see the WFCM. Add to Cart Add to Wishlist. Attendees will learn wfccm 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.
This webinar builds on the two previous Load and Load Path webinars and describes how connectors are used to create load paths in the structure and how the Wood Frame Construction Manual WFCM and calculated loads are used to determine connector type and size. The primary changes to the WFCM include: A comprehensive table listing section by section changes to the WFCM, including modifications to Supplement and Appendix material, is available at www.
Shear Wall Design Examples Several design tools and standards to assist engineers, architects, and building officials with the design of shear walls are available. Those provisions are relatively unchanged in ASCEresulting in net reductions to snow loads where unbalanced cases govern. Chapter 3 wvcm several prescriptive solutions derived from Chapter 2 load requirements. Use on a local area network or other network is not permitted. Foundation systems utilizing elevated piles will be emphasized.
Design values for structural lumber, structural glued laminated glulam timber, and fasteners were incorporated in the integral Supplement of the WFCM.
Browse FAQs for this topic. Its reference in the IBC and IRC will allow for its wfc in those jurisdictions adopting the latest building code. For More Information For more specific information on course content, please contact Dr.
The WFCM represents state of the art design for one and two family dwellings in regions with high winds, high seismic risk or large snow loads. The PDF Download is licensed per individual in which the individual can place on up to four electronic devices for their personal use. Shear wall story offset limits. Specifying and Constructing Floors to Accommodate Ceramic Tile and Stone The use of brittle floor covering materials requires carefully planning and coordination at the rough-framing design phase.
2012 Wood Frame Construction Manual for One- and Two-Family Dwellings & Commentary to the WFCM
Limits to the WFCM are based on the following: The design example uses plans from a 2-story residence as the basis for 20122 structural design to resist wind, seismic and snow loads. The WFCM provides engineered and prescriptive design requirements for wood frame construction used in one and two-family dwellings.
Chapter 2 provides minimum loads for buildings within the scope of this document for the purpose of establishing specific resistance requirements. Frank Woeste ator 2102 An integral Appendix of the WFCM still contains uplift strap and ridge strap capacity tables for those wishing to maintain that option.
This course will outline several resources available for shear wall design and compare design results. Several resources available for shear wall design will be discussed and design results will be compared using the various resources. This unit will provide a chapter by chapter overview of the WFCM which includes provisions for designing wood frame structures for wind, snow, and qfcm loads.
Traditional methods of providing for uplift resistance with additional tie-downs at shear walls can be cumbersome and expensive.
