AS 1684 SUPP 20 – National Timber Framing Code – Timber framing span tables – Unseasoned timber (alternative sizes) – Stress Grade F11 (Supplement to AS 1684-1992)

The supplements are for use with the National Timber Framing Code. They are computer-calculated tables according to stress grade and condition of dryness, which give the maximum allowable span for Australia and imported species according to their intended use or purpose in the building frame. Not all of these supplements will be required by designers. The content of each supplement is technically unchanged from the previous edition. The list of tables, list of supplements and scope and application clauses have been deleted from each supplement and incorporated into Supplement 0. Minor editorial changes have been made to the title and headings to some tables, for clarity. Persons who already have supplements will not need to purchase the revised supplements. Supplements 2, 3, 4, 5, 9 and 15 are bound with the Standard.
