Modelling environmental variation in Young’s modulus for Pinus radiata and implications for determination of critical buckling height. (2006)
Journal Article
Watt, M. S., Moore, J. R., Facon, J., Downes, G. M., Clinton, P. W., Coker, G., …Bown, H. E. (2006). Modelling environmental variation in Young’s modulus for Pinus radiata and implications for determination of critical buckling height. Annals of Botany, 98, 765-775. https://doi.org/10.1093/aob/mcl161

Background and Aims: Although density-specific stiffness, E/, (where E is Young's modulus and is wood density) is often assumed constant by the elastic similarity model, and in determination of critical buckling height (Hcrit), few studies have test...

An inexpensive instrument to measure the dynamic response of standing trees to wind loading (2005)
Journal Article
Moore, J. R., Gardiner, B. A., Blackburn, G. R. A., Brickman, A., & Maguire, D. A. (2005). An inexpensive instrument to measure the dynamic response of standing trees to wind loading. Agricultural and forest meteorology, 132(1-2), 78-83. https://doi.org/10.1016/j.agrformet.2005.07.007

A relatively inexpensive caliper type strain-gauge transducer was developed for measuring the dynamic behavior of tree stems and branches subjected to wind loading. Laboratory and field tests showed that the voltage signal produced by the transducer... Read More about An inexpensive instrument to measure the dynamic response of standing trees to wind loading.

Natural sway frequencies and damping ratios of trees: influence of crown structure (2004)
Journal Article
Moore, J. R., & Maguire, D. A. (2005). Natural sway frequencies and damping ratios of trees: influence of crown structure. Trees - Structure and Function, 19(4), 363-373. https://doi.org/10.1007/s00468-004-0387-y

Natural frequency and damping ratio were measured for nine plantation-grown Douglas-fir (Pseudotsuga menziesii Mirb. Franco) trees from the Oregon Coast Range under different levels of crown removal. Natural frequency of trees, in both their unpruned... Read More about Natural sway frequencies and damping ratios of trees: influence of crown structure.

Natural sway frequencies and damping ratios of trees: concepts, review and synthesis of previous studies (2004)
Journal Article
Moore, J. R., & Maguire, D. A. (2004). Natural sway frequencies and damping ratios of trees: concepts, review and synthesis of previous studies. Trees - Structure and Function, 18(2), 195-203. https://doi.org/10.1007/s00468-003-0295-6

Previous studies that measured the natural frequencies and damping ratios of conifer trees were reviewed and results synthesized. Analysis of natural frequency measurements from 602 trees, belonging to eight different species, showed that natural fre...
