Error determination of the formulas used for recalculation of wood strenth factors on 12% moisture content

Abstract

The article snows that while recalculating wood strength factor on the standard 12% moisture content the formulas used give a considerable error. Especially substantial error (7–9%) is ob-served at recalculation of the wood strength tested at the extreme values of the bound moisture range (0% and 30%). Depending on the wood moisture during testing the established error values permit to introduce the necessary corrections into the recalculation results according to the formulas. A method of more precise recalculation of wood strength on 12% moisture content is given in the article.
