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.

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. More Wood Sfcm Short Courses. Expand all Collapse all. Among the concerns is the number of tie-downs required for shear walls, which can present both cost increases and practical construction challenges. This article originally appeared in the Winter issue of Wood Design 20112 published by the Forest Products Society and is reprinted with permission.

Shear wall story offset limits. Browse FAQs for this topic. Understand the WFCM uses and scope limitations.

He may be reached at bshowalter awc. First Name Last Name. Attendees will learn the appropriate high wind, seismic, and snow loads to apply to residential structures based on code-referenced load standards.

There are separate wind speed maps for each Risk Category in the code, and Exposure D will become applicable again in hurricane prone regions. Those provisions are relatively unchanged in ASCEresulting in net reductions to wfvm loads where unbalanced cases govern.

JavaScript seems to be disabled in your browser. There are several design tools and standards to assist engineers, architects, and building officials with the design of shear walls. The local authority having jurisdiction should be consulted to determine whether conversion to a mph basis is permissible.

Design values for structural lumber, structural glued laminated glulam timber, and fasteners were incorporated in the integral Supplement of the WFCM. For More Information For more specific information on course content, please contact Dr. Learn the appropriate high wind, seismic, and snow loads to 22012 to residential structures based on code-referenced load standards.

STRUCTURE magazine | WFCM Changes

This article provides an overview of the significant changes in the WFCM relative to the previous edition. In addition, this presentation will provide an overview of the significant changes in the WFCM relative to the previous edition.

A range of structural elements are included such as sawn lumber, structural glued laminated timber, wood structural panel sheathing, I-joists, and trusses.

Revised map contours will influence Seismic Design Categories of some geographic areas. WFCM Editions Separate documents address wind design requirements in,and mph Exposures B and C wind zones for other wind speeds and exposures see the WFCM.

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

The design example uses plans from a 2-story qfcm as the basis for a structural design to resist high wind, seismic, and snow loads. 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.

Be able to analyze format and content within the WFCM. For a volume license the PDF is licensed to the person in which it is assigned. The WFCM provides engineered and prescriptive design requirements for wood frame construction used in one and two-family dwellings.

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

Using plans from a 2-story residence, participants prescriptively design the structure to resist high wind, seismic, and typical residential gravity loads. Your message Submit Comment. Shear Wall Design Examples Several design tools and standards to assist engineers, architects, and building officials with the design of shear walls are available.

Leave a Comment Click here to cancel reply. A desire to investigate the inherent uplift capacity of nailed wood structural panel shear walls was the impetus for wfck of this design method. Understand hold down design. For fastener design values, the NDS is the reference standard. This course will outline several resources available for shear wall design and compare design results.

Suppliers of building products used in the residential construction and their sales staff may benefit as well by enhancing their knowledge of a code-conforming whole building design. In general, the framing systems described in the WFCM utilize repetitive member wood assemblies. Distribution of the PDF is not permitted. The limitations of applicability are provided in Chapters 2 and 3.

The design example uses plans from a 2-story residence as the basis for a structural design to resist wind, seismic and snow loads. This presentation will provide an overview of the significant changes in the WFCM relative to the previous edition.

This unit will provide wfccm overview of the significant changes to the DCA 6 and include several examples showing application of the guide. An integral Appendix of the WFCM still contains uplift strap and ridge strap capacity tables for those wishing to maintain that option. Vertical and lateral load paths will be described including the role 2102 shear walls in buildings. 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 WFCM includes design and construction provisions for connections, wall systems, floor systems, and roof systems. Shear wall story offset provisions were clarified in the WFCM.

We recommend users of early versions of Internet Explorer to update to Version 10 or later.

Several resources available for shear wall design will be discussed and design results will be compared using the various resources. Traditional methods of providing for uplift resistance with additional tie-downs at shear walls can be cumbersome and expensive. Limits to the WFCM are based on the following: Frank Woeste ator e-mail: A range of structural elements are covered, including sawn lumber, structural glued laminated timber, wood structural sheathing, I-joists, and trusses.
