Web Program to Predict Residual Strength and
Serviceability for Fire-Retardant Treated or Untreated Wood Exposed
to High Temperatures Using Kinetic Models
This program performs the calculations necessary to implement the
model developed and verified in a series of papers discussing
kinetic-based modeling of the material property modulus of rupture
(MOR) for wood that has been treated with a fire-retardant (FRT wood). See
Lebow and Winandy (Wood and Fiber Science, 1999, 31(1):49-61)
Winandy and Lebow (Wood and Fiber Science, 1996, 28(1):39-52). Other
resources about the FRT wood degradation program are available on the
USDA, Forest Service, Forest Product Laboratory's
Properties of Wood website or via publication searches on
the Forest Product Lab's website.
The program will calculate kinetic parameter estimates (as described
in the above papers), their standard
errors, and plot predictions on how the modeled FRT wood will perform
in service over a period of time if exposed in Madison, Wisconsin.
A one-year typical roof exposure for Madison has been described in a
and Beaumont (1995, FPL RP-543). Additional temperature load histories
of various wood components in traditional light-framed structures has
been studied and are presented in
Barnes and Hatfield (2000, FPL RP-589).
