Determining Allowable Design Values for Wood

The strength of wood increases with a reduction in the moisture content. Reference design values for sawn lumber assume maximum moisture content of 19%. Wood with a moisture content of 19% or less is considered dry. Kiln dried or seasoned wood would be considered dry as long as it hasn’t been exposed to weather long enough to cause re-saturation.
