2012 WFCM PDF

  • No Comments

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.

This webinar will be a continuation of the Loads wtcm and use the loads developed previously to illustrate the importance of load path continuity in buildings.

Capacities are based on provisions in the NDS and have been verified by full scale testing. 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. Be able to wccm format and content within the WFCM. Provisions contained in this document that are not included in the IRC are considered good practice recommendations.

Understand the WFCM uses and scope limitations. The workbook heavily references the WFCM to aid in understanding how to use the time-saving tools and tables provided therein. Using plans from a 2-story residence, participants prescriptively design the structure to resist high wind, seismic, and typical residential gravity loads.

Limits to the WFCM are based on the following: Expand all Collapse all. Add to 20012 Add to Wishlist. The primary changes to the WFCM include: 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 WFCM Editions Those provisions are relatively unchanged in ASCEresulting in net reductions to snow loads where fwcm cases govern. Traditional methods of providing for uplift resistance with additional tie-downs at shear walls can be cumbersome and expensive.

Note that Chapter 2 also contains some necessary construction details. You must have JavaScript enabled in your browser to utilize the functionality of this website. Be familiar with additional resources that are available. Attendees will learn to use checklists and detailing summaries to ensure a complete load path is prescriptively designed for the wall and floor 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.

There are separate wind speed maps for each Risk Category in the code, and Exposure D will become applicable again in hurricane prone regions. Chapter 3 provides several prescriptive solutions derived from Chapter 2 load requirements. The latter tends to provide more conservative results.

Shear Wall Design Examples Several design tools and standards to assist engineers, wrcm, and building officials with the design of shear walls are available.

Attendees will learn the appropriate high wind, seismic, and snow loads to apply to residential structures based on code-referenced load standards. 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.

In general, the framing systems described in the WFCM utilize repetitive member wood assemblies. He may be reached at bshowalter awc.

Identify and understand the basic shear wall system to resist wind and seismic loads. 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. This 20112 will outline several resources available for shear wall design and compare design results.

For a volume license the PDF is licensed to the person in which it is assigned. This webinar builds on the wfm previous Load, Load Path, and Connections webinars to describe how loads must be transferred through the building to reach the foundation system.

A range of structural elements are covered, including sawn lumber, structural glued laminated timber, wood structural sheathing, I-joists, and trusses. Several resources available for shear wall design will be discussed and design results wfxm be compared using the various resources. We recommend users of early versions of Internet Explorer to update to Version 10 or later.

For fastener design values, the NDS is the reference standard. Separate documents address wind design requirements in,and mph Exposures B and C wind zones for other wind speeds and exposures see the WFCM.
