This supplemental report has been written to present aspects of the experimental testing not fully described in the final report for this project, and discusses in greater detail the recommendations for future work made in that report. Much of the experimental data gathered under this project and its predecessor has not been fully analyzed. It contains within it much more information regarding the behaviour of structural dimension lumber. Knowledge of this behaviour is important because the wood industry must be prepared to provide adequate and relevant performance information to gain code acceptance under the new proposed objective-based national building code.
