Nore (Eds.), Proceedings from the 13th World Conference on Timber Engineering (2023) (780-786). https://doi.org/10.52202/069179-0107

This paper discusses the situations in which timber species might be combined in commercial combinations, and the considerations relating to strength grading work. It is expected that more species combinations will be developed in the years to come,... Read More about Considerations for grading species combinations.

Considerations for grading species combinations. The example of Douglas fir with larch in Ireland and UK (2023)
Conference Proceeding
Gil-Moreno, D., Ridley-Ellis, D., & Harte, A. M. (2023). Considerations for grading species combinations. The example of Douglas fir with larch in Ireland and UK. In A. Q. Nyrud, K. A. Malo, & K. Nore (Eds.), Proceedings from the 13th World Conference on Timber Engineering (2023) (773-779). https://doi.org/10.52202/069179-0106

This paper examines the grading of Douglas fir (Pseudotsuga menziesii) and larch (Larix spp.) as a strength grading species combination for the growth area formed by Ireland and the UK. The two genera produce higher timber quality than Sitka spruce (... Read More about Considerations for grading species combinations. The example of Douglas fir with larch in Ireland and UK.

Test Machine Effect in the determination of modulus of elasticity for strength-graded timber (2021)
Conference Proceeding
Gil-Moreno, D., Ridley-Ellis, D., & Harte, A. M. (2021). Test Machine Effect in the determination of modulus of elasticity for strength-graded timber. In WCTE 2021: World Conference on Timber Engineering Proceedings

This paper investigates if the relationship between the global and local moduli of elasticity (MoE), measured in bending tests, is affected by the test machines employed, and how that may influence strength grading. The ultimate aim is to study the p... Read More about Test Machine Effect in the determination of modulus of elasticity for strength-graded timber.

Perception and use of timber in construction: A case study of Ireland and the UK (2021)
Conference Proceeding
O'Ceallaigh, C., Gil-Moreno, D., Ridley-Ellis, D., & Harte, A. M. (2021). Perception and use of timber in construction: A case study of Ireland and the UK. In WCTE 2021: World Conference on Timber Engineering Proceedings

A survey was carried out to examine the perception of timber in construction among industry stakeholders within northwest Europe. The survey received responses from 17 countries in total. The total results of all respondents are presented along with... Read More about Perception and use of timber in construction: A case study of Ireland and the UK.

Influence of knot area indexes on tension strength of Sitka spruce (2019)
Conference Proceeding
Gil-Moreno, D., Ridley-Ellis, D., & Harte, A. M. (2019). Influence of knot area indexes on tension strength of Sitka spruce. In Proceedings of the 15th Annual Meeting of the Northern European Network for Wood Science and Engineering

It is well known that knots can reduce the strength of timber, and the selection of “critical section” for testing to EN 408 and EN 384 is typically based on the size and position of knots. In Ireland, the visual strength grading Standard IS 127 spec... Read More about Influence of knot area indexes on tension strength of Sitka spruce.

Use of Nondestructive Techniques for Determination of Tension Parallel-to-Grain Properties of Spruce (2019)
Conference Proceeding
Gil-Moreno, D., O'Ceallaigh, C., Ridley-Ellis, D., & Harte, A. M. (2019). Use of Nondestructive Techniques for Determination of Tension Parallel-to-Grain Properties of Spruce. In Proceedings: 21st International Nondestructive Testing and Evaluation of Wood Symposium, Freiburg, Germany 2019 (233-240)

The paper presents a study of the tension properties of Irish-grown Sitka spruce. Fifty timber pieces were destructively tested having resonant frequency and knots measured. The aim was to improve knowledge of the performance of spruce in tension and... Read More about Use of Nondestructive Techniques for Determination of Tension Parallel-to-Grain Properties of Spruce.

Using the right Modulus of Elasticity to get the best grades out of softwood timber species in Great Britain (2016)
Conference Proceeding
Gil-Moreno, D., Ridley-Ellis, D., & McLean, P. (2016). Using the right Modulus of Elasticity to get the best grades out of softwood timber species in Great Britain. In WCTE 2016 World Conference on Timber Engineering e-book Full Papers

The correct characterisation of modulus of elasticity in bending is fundamental for timber grading, especially when that property limits the allocation to a strength class. The aim of this paper is to empirically determine the relationship between EN...

Strength class of minor conifer species, as estimated from log acoustic measurements, small-clear data and knowledge of wood property variation (2014)
Conference Proceeding

It is well known that wood properties vary from species to species. Additionally, trees grow wood in response to their requirement to grow in a certain environment. Therefore, timber properties also vary by region, by forest practice, and by the chan...
