Timber Stress Grading: Analysis of Existing Timber Strength Grouping and Strength Classification Systems

摘要

In an exercise to make recommendations for a strength grouping system acceptable for international adoption by UNIDO for work in developing countries, a review of existing classification systems in the world was made. It appears that many countries have either adopted the Australian system of groupings or have used it as the basis for developing their own system. It has long been a problem to present structural timber data to the end-user in an appropriate fashion. A technique devised to minimize the problem is grouping.
