WWW Computer Program for
Adjusting Mechanical Properties of
Dimension Lumber for Changes
in Moisture Content
Lumber strength properties vary with changes in moisture content.
This program allows you to predict a property (P2) of dimension lumber
at a target moisture content (MC2) given that you know the value of
the property (P1) at an initial moisture content (MC1). Properties
and models for which this program provides estimates include:
- Modulus of Rupture (ASTM D-1990 and Quadratic Surface Models)
- Modulus of Elasticity (ASTM D-1990, Simple Interest, and
Compound Interest Models)
- Ultimate Tensile Strength (ASTM D-1990 and Quadratic Surface Models)
- Compression Parallel to the Grain (ASTM D-1990 and Quadratic Surface Models)
- Compression Perpendicular to the Grain (ASTM D-2915)
- Shear (ASTM D-2915)
You may choose either of the following methods of running the program:
