A range of structural elements is covered, including sawn lumber, structural glued laminated timber, wood structural panel sheathing, I-joists, and trusses. Lower wind speed categories e. Table 1a. Tables 1a and 1b also show the roof coefficients as implemented for WFCM chapters 2 and 3.

WFCM Chapter 2 uses the maximum magnitude suction loads for roof slopes between 7 and 45 degrees in Roof Zones 1, 2, and 3. WFCM Chapter 3 further simplifies the roof loading requirements by combining Roof Zones 2 and 3 into an end zone and reducing the magnitude of Zone 3 loads by limiting rake overhangs. Figure 3. Roof Rake Overhangs Rake overhang provisions were revised to clarify terminology and limit rake overhang lookout blocks to 9 inches previously limited to 12 inches based on increased wind pressures Figure 4a.

Rake overhang outlooker provisions were expanded to tabulate requirements for overhang spans of 12, 16 and The smaller span cases were added to address increased wind pressures and remove conservatism associated with tabulated requirements based only on assumed inch overhang span.

Fastener uplift capacity is the lesser of withdrawal and head pull through. Table 2.

Comparison of RSRS to 8d common nailing patterns for high wind. Shear walls using gypsum wallboard are subject to the following limits underlines show clarifying text added to WFCM : Gypsum wallboard walls having aspect ratios exceeding 1.

Requirements for shear walls with blocked wood structural panel sheathing are now tabulated assuming a maximum shear wall segment aspect ratio for wind of previously 3. However, the WFCM still allows aspect ratio increases up to 3.

Structural elements beyond these limitations shall be designed in accordance with accepted engineering practice. While WFCM provisions are intended primarily for detached one- and two-family dwellings due to the floor live load assumption associated with those occupancies, many of the WFCM provisions for specific geographic wind, seismic, and snow loads may be applicable for other buildings. For example, wind provisions for sizing of roof sheathing, wall sheathing, fastening schedules, uplift straps, shear anchorage, shear wall lengths, and wall studs for out of plane wind loads are included in the WFCM and are applicable for other use groups within the load limitations of the WFCM tables.

Similarly, roof rafter size and spacing for heavy snow and shear wall lengths and anchorage for seismic are applicable within the load limitations of the WFCM tables.

Examples of non-residential applications include single-story wood structures or top stories in mixed-use structures in Risk Categories I or II.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. Learn to use checklists and detailing summaries to ensure a complete load path is prescriptively designed.
