Strategic Integrated Research in Timber: Getting the most out of the UK's timber resource. (2009)
Journal Article
Ridley-Ellis, D., Moore, J., Lyon, A. J., Searles, G. J., & Gardiner, B. A. (2009). Strategic Integrated Research in Timber: Getting the most out of the UK's timber resource. Non-conventional Materials and Technologies,

Sitka spruce (Picea sitchensis) is the United Kingdom’s main commercial tree species accounting for nearly one-third of the UK's total woodland area and half of its conifer estate. Sawn timber from this species readily grades to the C16 strength clas... Read More about Strategic Integrated Research in Timber: Getting the most out of the UK's timber resource..

Random acts of elasticity: MoE, G and EN408. (2009)
Presentation / Conference Contribution
Ridley-Ellis, D., Moore, J., & Khokhar, A. M. (2009). Random acts of elasticity: MoE, G and EN408.

The paper examines the variation in modulus of elasticity (MoE) and shear modulus (G) within sawn timber and the implications for testing timber in accordance with EN408:2003. A combination of mechanical testing and simple analytical modelling is us... Read More about Random acts of elasticity: MoE, G and EN408..

Determining the Shear Modulus of Sitka Spruce from Torsion Tests (2008)
Journal Article
Khokhar, A. M., Zhang, H., Ridley-Ellis, D., & Moore, J. (2008). Determining the Shear Modulus of Sitka Spruce from Torsion Tests. Timber Engineering,

This paper presents details of the experimental method, and preliminary results from, a series of torsion tests undertaken to evaluate the shear modulus of Sitka spruce (Picea sitchensis) timber. Direct torsion tests were used to determine the variat... Read More about Determining the Shear Modulus of Sitka Spruce from Torsion Tests.

Recruiting Women into Scottish Wood Chain Industries (2008)
Journal Article
Ridley-Ellis, D., MacPherson, S., & Thomson, E. (2008). Recruiting Women into Scottish Wood Chain Industries. Timber Engineering, 1, 477-485

In common with many countries, the composition and attitudes of Scotland’s population are changing. It is the regions where the industries in the wood products value chain are based that are expected to change most dramatically. These industries cont...

Online learning for the forest and timber industries. (2008)
Presentation / Conference Contribution
Ridley-Ellis, D., Nolte, S., & Condon, P. (2008). Online learning for the forest and timber industries. In 10th World Conference on Timber Engineering 2008 (461-469)

Online learning offers advantages for all levels of training and development in the timber industries, from new recruits at technician level to chartered professionals. Learners and employers both value the flexibility it affords, while educators val... Read More about Online learning for the forest and timber industries..

Dynamic performance of multi-webbed engineered timber joists (2008)
Journal Article
Bahadori-Jahromi, A., & Ridley-Ellis, D. (2008). Dynamic performance of multi-webbed engineered timber joists. Journal of the Institute of Wood Science, 18, 87-93. https://doi.org/10.1179/wsc.2008.18.2.87

The introduction of engineered beams offered longer span, lower cost joists in comparison to traditional solid timber sections; however, vibration criteria in the design codes may significantly reduce the permissible span of joists for domestic const...

Strength grading and the end user – lessons from the SIRT project at Napier University (2008)
Presentation / Conference Contribution
Ridley-Ellis, D., Moore, J., & Lyon, A. J. (2008). Strength grading and the end user – lessons from the SIRT project at Napier University.

The paper reviews the research that has been undertaken by the Strategic Integrated Research in Timber (SIRT) project at Napier University, with reference to the technologies, techniques and approaches required to grade the UK’s timber resource accor...

Properties of UK-Grown Sitka Spruce: Extent and Sources of Variation. (2008)
Journal Article
Moore, J., Lyon, A. J., Ridley-Ellis, D., & Gardiner, B. A. (2008). Properties of UK-Grown Sitka Spruce: Extent and Sources of Variation. Timber Engineering,

Structural timber produced from Sitka spruce plantations in the UK typically achieves the requirements for the C16 strength class. However, very little is known about the variability of this plantation resource, or the factors that contribute to this...
