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 National Design Specification (NDS) for Wood Supplement. To obtain the correct values, see NDS Table 4A at https://awc.org/pdf-viewer/?idp=4126&idf=4. 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.
