Determining Allowable Design Values for Wood

The allowable design value is the value that should be used when sizing/designing wood structural components. This course teaches the methodology for adjusting the reference design values for all significant factors in order to arrive at the allowable design value. Remember: • Reference values are baseline values that you start with.
