Alternative UK timber species (2021)
Book Chapter
Adams, S., & Ridley-Ellis, D. (2021). Alternative UK timber species. In Timber 2021 Industry Yearbook (104-111). TRADA

Steven Adams and Dan Ridley-Ellis discuss the findings of a recent research project into the properties and potential uses of lesser-used species in the UK.

Some thresholds for grading British grown spruce to optimised strength classes using longitudinal resonance (2018)
Presentation / Conference Contribution
Ridley-Ellis, D., Adams, S., & Lehneke, S. (2018, August). Some thresholds for grading British grown spruce to optimised strength classes using longitudinal resonance. Presented at World Conference on Timber Engineering, Seoul, Republic of Korea

The main commercial species in the UK and Ireland is Sitka spruce (Picea sitchensis), which is graded in combination with a small amount of Norway spruce (P. abies). It is typically graded to the European strength class C16, but actually has superior...

The daily cycle of moisture content expansion and contraction in UK-grown Sitka spruce trees (2018)
Presentation / Conference Contribution
Adams, S., & Ridley-Ellis, D. (2018, June). The daily cycle of moisture content expansion and contraction in UK-grown Sitka spruce trees. Paper presented at Timber 2018

The diameter of five dominant Sitka spruce (Picea sitchensis) trees at Griffin Forest (near Aberfeldy, Scotland) were monitored at two minute intervals with dendrometers between April 2008 and October 2012. This experiment was designed to investigate... Read More about The daily cycle of moisture content expansion and contraction in UK-grown Sitka spruce trees.

Thinking beyond the usual strength grades – with examples of British spruce and larch (2016)
Presentation / Conference Contribution
Ridley-Ellis, D., Adams, S., & Lehneke, S. (2016, August). Thinking beyond the usual strength grades – with examples of British spruce and larch. Presented at World Conference on Timber Engineering (WCTE 2016)

This paper summarises the processes and normative requirements involved in grading of structural timber, and outlines a number of areas in which matters may be improved, so as to make better use of the true properties of the timber resource used. The... Read More about Thinking beyond the usual strength grades – with examples of British spruce and larch.
