Resources provide a simplified system to determine allowable joist and rafter spans in one- and two-family dwellings, and the companion supplements for tabulating allowable bending and modulus of elasticity design values for visually graded and mechanically graded dimension lumber.
First you need to get a few things: Code book; AWC’s Span Tables for Joists and Rafters (this assigns allowable spans to various combinations of E and Fb); and a copy of Design Values for Joists and Rafters (this has Fb and E values for various species, sizes and grades of dimension lumber).
Online and mobile-based calculators for determining joist and rafter spans, design connections, heights and areas, sound transmission, and energy efficiency compliance.
AWC Web-Based Calculators and Other Resources. American Wood Council's website is a treasure trove of resources for architects, engineers, code officials, builders, etc. to aid in the design and plan review of wood projects; most of which are available for free.
22 Νοε 2019 · The American Wood Council (AWC) Span Calculator for Wood Joists and Rafters (Span Calc) performs calculations for all species and grades of commercially available softwood and hardwood lumber as found in the 2018 National Design Specification® (NDS®) for Wood Construction Supplement: Design Values for Wood Construction.
This application provides a web-based approach to calculating capacities for wood connections per the American Wood Council standards.
24 Σεπ 2024 · The American Wood Council Span Calculator is a tool for determining the allowable spans of wood beams and joists for various applications. How Does The Span Calculator Work? It calculates maximum spans based on wood species, grade, and load conditions, ensuring safe structural design.
