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

$80.00

In general, the framing systems described in the WFCM utilize repetitive member wood assemblies. The WFCM includes general information on loads and resistances. The limitations of applicability are provided in Chapters 2 and 3. Chapter 2 provides minimum loads for buildings within the scope of this document for the purpose of establishing specific resistance requirements. Note that Chapter 2 also contains some necessary construction details. These details have been derived from typical code provisions and are included in Chapter 2 for the convenience of the designer. Chapter 3 provides several prescriptive solutions derived from Chapter 2 load requirements. Therefore, it is perfectly acceptable to use Chapter 3 provisions for parts of a design and Chapter 2 for other parts.

The primary changes to the 2012 WFCM include:

  • Design load provisions are based on ASCE 7-10
  • Wood structural panels are permitted to resist wind uplift
  • Shear wall story offset provisions are clarified
  • Design values for lumber, engineered lumber and fasteners are based on the 2012 NDS
  • Engineering design values for horizontal diaphragm  and vertical wall assemblies are in accordance with SDPWS-08
  • Header tables include dropped and raised header conditions
