[CANUFNET] Hand pull testing

[Naomi Zurcher via CANUFNET]

Hi Rob:

There was a very good article in Arboriculture & Urban Forestry by Ken James on Biomechanics. The reference material reviewed and listed might be of assistance in your project. Here's a link to the full pdf of the article:
https://www.researchgate.net/publication/286457330_Tree_Biomechanics_Literature_Review_Dynamics

In addition, another paper by Ken James entitled "A Dynamic Structural Aanalysis of Trees Subject to Wind Loading has a section on the Tree Pull Test
https://minerva-access.unimelb.edu.au/bitstream/handle/11343/35741/265448_Ken%20James%20Thesis.pdf?sequence=1

Hope this helps

kind regards
naomi

As part of our advanced risk assessment techniques, we will perform a hand pull test on smaller trees to assess soil, root or trunk movement. We’re curious as to the amount of force necessary to adequately represent a wind speed of up to 80 km/h. Any information on this subject would be appreciated.
