There are currently inconsistencies in the implementation of design for compression perpendicular-to-grain (C-perp) in the Canadian engineering design in wood code. Not only does this make the design code confusing, but this inconsistency is also a hindrance to the introduction of higher C-perp strength values for MSR lumber. For some engineered wood applications, higher design stresses may result in unsafe conditions. Without revisions to the design procedures, it would not be possible to allow the use of higher C-perp design strengths for applications where it is warranted. The study focused on resolving the inconsistencies in implementation of C-perp design for solid sawn lumber and glued laminated timbers. A testing program consisting of short term and constant load tests were conducted. Finite element analysis of typical C-perp stress conditions were also performed. This work was under the guidance of a CSA-O86 task group on C-perp design. The findings were submitted to the task group and proposed code changes were developed. Presentations on the proposed changes were then presented at the November 1993 meeting of the CSA Technical Committee on Engineering Design in Wood. If the codes changes are approved, design for C-perp will be more rational and refined, especially for engineered wood construction. The code change proposal also includes higher C-perp design values for C-perp for machine stress rated S-P-F lumber.
