Standard Specification for Computing Reference Resistance of Wood-Based Materials and Structural Connections for Load and Resistance Factor Design
STANDARD published on 1.5.2023
Why Redline?
A PDF redline is a quick and easy way to compare all of the changes between the current, active standard and the previous version.
With a redline you'll immediately see:
Save Time and Trouble!
With a Redline you no longer have to spend time trying to determine what has changed in the new standard! Redlines save you time and ensure you see what the changes are to the standard.
Price
When you select the "Active + Redline" option you get both documents! Best of all, the cost of an Active + Redline is only slightly more than buying the Active Standard by itself.

This specification covers procedures for computing the reference resistance of wood-based materials and structural connections for use in load and resistance factor design (LRFD). Parameters required for the derivation of reference resistance are presented. These parameters include the distribution percentile, coefficient of variation, data confidence factor, and reliability normalization factor. The shape and scale parameters of the two-parameter Weibull distribution shall be established to define the distribution of the material resistance. The data confidence factor accounts for uncertainty associated with data sets. This factor, which is a function of coefficient of variation, sample size, and reference percentile, is applied as a multiplier on the distribution estimate. The reliability normalization factor is used to adjust the distribution estimate to achieve a target reliability index. The reliability normalization factor is the ratio of the computed resistance factor to the specified resistance factor, adjusted by a scaling factor.
