This standard provides the minimum design requirements for new log structures, including structural, thermal envelope and fire-resistance provisions. Notable changes from the 2017 edition include: New tabulated reference provides the weight per square foot of wall surface area of log-walls at 21-percent design moisture content by average width and specific gravity. Additional factors noted to adjust moisture content and\/or nominal size\/ shape to average width. Section 302.2.4 Notching and boring: Now provides multiple paths (e.g., prescriptive, calculated) for acceptance of notching and boring of beams. Two new illustrations replace Figure 302.2.4. Section 302.3 Mechanical connections and fasteners: Updated prescriptive path compliance for ANSI\/AWC specification in the National Design Specification (NDS), alternative evaluation path for proprietary (nonconforming) fasteners, and specified analysis for wood dowels. New tabulated reference providing the bearing capacity (lb\/in) of wall-logs, which is useful for calculating the continuous load path. Updated US Climate Zone map to reflect updates in the 2021 IECC. Improved criteria for settling devices to ensure structural integrity. Section 305 Thermal envelope: Updated to clarify the relationship to infiltration (Section 306) and the relationship to the 2021 IECC Commercial and Residential provisions.
