Wisconsin Administrative Code

Caution: Do not use the Southern Pine design values in the new UDC Appendix A for sizing joists and rafters. They do not reflect the reduced values in the newly adopted 2015 National Design Specification for Wood Supplement. To obtain the correct values, go to http://www.awc.org/pdf/codes-standards/publications/nds/AWC-NDS2015-Supplement-ViewOnly-1411.pdf and scroll to Table 4A. Those values may be increased 15% for repetitive joist or rafter use (due to load sharing by 3 or more members spaced 24" o.c. or less) and an additional 15% for rafter use (due to snow load duration increase).

It is suggested that you click on a PDF icon when using the UDC Appendix to properly view diagrams, tables, and text.
