Oregon Wood Construction Wind and Seismic Code 2021
Overview The International Residential Code (IRC) provides comprehensive requirements for the construction of residential buildings, including guidelines for roof-ceiling construction. Chapter 8 of the IRC includes span tables for joists and rafters, which specify the allowable spans for various sizes, grades, and species of lumber used in residential construction.
The 2021 Oregon Joists and Rafters Span Tables Code adopts Chapter 8 of the IRC 2018 with specific amendments tailored to Oregon’s unique conditions. These modifications ensure that joists and rafters in Oregon are designed and installed to meet high standards of safety and performance, addressing local environmental and construction requirements.
