Abstract
In structural engineering literature, the correlation between, knot ratios and MoR, has been interpreted intuitively as a causal relationship. The assumption of causal correlation between knots and MoR has led to some visual grading codes treating knots sizes as being directly related to MoR. Strength ratios associated with knots in bending members have been derived as the ratio of moment-carrying capacity of a member with cross section reduced by its largest knot to the moment-carrying capacity of the member free of knots. This approach is at least partially adopted by structural engineers assessing in situ timber. The purpose of this technical note is to document the rationale behind a brief investigation into the idea of knots acting as voids within timber joists and to report how effective this approach is at estimating the bending strength of timber joists.
