Jun 29, 2025 · When constructing buildings in regions affected by cold climates, understanding the frost line is critical for long-term structural integrity and safety. Except where otherwise protected from frost, foundations and other permanent supports of buildings and structures shall be protected from frost by one or more of the following methods: Jul 17, 2023 · 1. 3. This page details data on the AFI - Air Freezing Index a common metric for determining the freezing severity of the winter season. 070 IRC Chapter 3, Table R301. The considerations that a local jurisdiction can use when developing its “frost line depth” include, but are not limited to, air freezing index, soil type, water table depth, local historical data, and field ign tables, climate maps, and other neces-sary data to furnish a complete frost-protection design. Frost depth: 12” Minimum roof snow load: 25 psf Minimum roof load – non reducible Ground snow: 30psf Drift calculations required per ASCE 7-16. ASCE 32-01, “Design and Construction of Frost-Protected Shallow Foundations”, contains several different, code approved, methods to design shallow foundations of various types. To assist with future model developments, multiple frost-susceptible soil types were tested with a variety of moisture conditions. Oregon Design Criteria Hub The Oregon Design Criteria Hub is an interactive mapping tool that provides site-specific climatic and geographic design criteria for construction projects permitted using the Oregon Residential Specialty Code (ORSC) and the Oregon Structural Specialty Code (OSSC). tjmiithy
