Predicting the Bending Yield Strength of Timber Frame Pegs
Publication: Journal of Materials in Civil Engineering
Volume 31, Issue 3
Abstract
Timber frame connections commonly use mortise and tenon connections secured by wooden pegs. The calculation of peg connection strength depends upon the joint dimensions, material properties of the mortise and tenon, and the bending yield strength of the peg. The purpose of this technical note was to measure the bending yield strength of a variety of pegs encompassing the range of wood species and diameters found in timber frame construction. A regression analysis of the bending yield strength data used a series of two-factor and single-factor power and linear equations using specific gravity and diameter as independent variables. A linear equation to estimate the bending yield strength was chosen based upon similarity of results and simplicity of calculation.
