TFEC: Research Reports

Measuring the Bending Yield Strength of Timber Frame Pegs
The design of traditional timber frame connections relies heavily on the use of wood pegs to resist shear forces. Wood pegs differ from the metal fasteners traditionally used in the National Design Specification for Wood Construction (NDS) by having lower strength and stiffness properties and including a fifth yield mode in the design equations (TFEC 2010, AWC 2015). An interesting advantage of the lower strength of pegs is the ability to reduce the spacing requirements used for steel fasteners. One of the key properties in the design of wood peg connections is the dowel bending yield strength, Fyb. This term is present in both Mode III and IV yield limit equations in the NDS.
