Please note again: Only those who subscribe to our newsletter list will continue to receive regular information about the SAG Baumstatik workshops! Please register!
The 22nd SAG workshop will take place in Bad Vöslau near Vienna on 4 June 2024 and will deal with the topic of ‘Sonic tomography – comparative measurements’. The effect of different measuring points on the image produced will be compared and the creation of the images, their interpretation and the path from the image to the assessment of safety against fracture will be discussed.
After the lively discussion about root detection in the SAG WhatsApp group, we would like to invite you to a workshop on the topic.

From July 17th to 22nd, SAG is holding a workshop on the subject of pulling tests.
Experts and users want to gather and expand their experiences in small groups in an idyllic environment and also discuss them critically, e.g. new results from science and research on the subjects
– Tree morphology
– case studies of pulling special trees
– Material properties of different trees
– Wind and tree interaction
– and much more.
During the week renowned scientists will join us, such as Karl Niklas, Steffen Rust, Francesco Ferrini and many others in an informal and friendly atmosphere.
Current studies and models for the dynamic response of trees in natural winds
Program and speakers (all times CET/MEZ = UTC + 1/Berlin)
8:30 Introduction
8:45 Damien Sellier
Tree sway frequency and damping – finite element modelling and age effects
Damien Sellier is computational modeller at Scion – the New Zealand Forest Research Institute – in Rotorua. His research focuses on developing physics-based models to study tree physiology, wood formation and wood mechanics. He is particularly interested in digital models capturing the real-life complexity of tree organisms. He has a PhD in mechanical engineering; his thesis was the numerical analysis of tree aerodynamic behaviour under wind turbulence in a forest canopy.
9:15 discussion
9:45 coffee break
10:15 Daniel Burcham
Changes in the dynamic properties of trees in natural winds after pruning
Daniel Burcham is the Deputy Director for Urban Trees at the National Parks Board in Singapore. In his research he is studying the behaviour of trees in natural winds.
11:00 discussion
11:30 coffee break
12:00 Toby Jackson
The motion of trees in the wind. A data synthesis
Toby Jackson is currently a postdoc in Cambridge supervised by Prof David Coomes. He is working on the effects of wind on tropical forests. This 4 year NERC funded project uses LiDAR to map forest structure and so model wind flow over a complex forest landscape. He will also be measuring wind speeds and the bending response of tall trees in situ.
12:30 discussion
1:00 lunch break
2:00 Ebba Dellwik
The SingleTree Experiment: An experimental characterization of the wind-tree interaction of an open-grown oak tree
Ebba Dellwik is senior researcher in the Meteorology and Remote Sensing Section in the Wind Energy Department of the Technical University of Denmark. Ebba leads DTU’s research on forest and tree aerodynamics and the study of their impact on the wind conditions. Her focus is on both full-scale and wind tunnel experimental studies with a scope of improving the parameterization of trees in weather and flow models.
2:30 Nikolas Angelou
Mean drag estimation on a full-scale tree using tree-mounted sensors and scanning wind LiDAR measurements
Nikolas Angelou is a postdoctoral researcher in the Meteorology and Remote Sensing Section in the Wind Energy Department of the Technical University of Denmark. His scientific interest is on the investigation of the wind conditions in the atmospheric boundary layer, experimental flow studies using scanning wind LiDAR, wind-tree interactions and in general flow characterization for wind engineering applications.
3:00 discussion
3:30 afternoon coffee break
4:00 Dirk Schindler
Modelling tree responses to turbulent wind from in-situ measurements
Dirk Schindler is the professor for environmental meteorology at the university of Freiburg. From in-situ measurements on trees he derives new models to describe wind and tree interaction.
4:30 discussion
5:00 closing remarks, goodbye

For September, we actually planned our 18th SAG workshop in Utrecht, the Netherlands. Due to the general situation caused by the corona pandemic, we unfortunately have to postpone the event to indefinite. We are trying to find an alternative date in 2021.
– continuing on developing technical standards for pulling tests and their evaluation
This time we would like to continue working on the SAG standard based on our experience and previous workshops. In the second workshop on this topic, the results of the individual working groups will be presented, discussed and further developed. The day will start with the presentations of the working groups. In addition we would like to offer room for any further topics that are not yet part of the standards. Afterwards we will discuss in small groups as well as in the plenary before we are going to coordinate the further work.

Topic:
SAG Standards for the Pulling Test Method
– developing technical standards for pulling tests and their evaluation
This time, we want to exclusively focus on what we have already learned from our experience and previous workshops. We would like to use this information together with the work already done so far to get the SAG standards really a big step ahead. Therefore, we would like to use this workshop to put together the frame of the SAG standard and finish the workshop with a draft version of it.
The plan is to work in the full group on Monday and start with presentations on specific topics like safety during pulling tests, generating usable data during the test, evaluating the data and the minimum level of knowledge to be gained in training before starting with pulling tests. Additionally, we would like to see the ethics discussion be continued that has been started in 2010 in Aschaffenburg and become part of the standards.
In the morning of June 4th 2019 the results of the first SAG funded wind tunnel study on the effect of adjacent trees on the wind load will be presented and their application to the evaluation will be discussed. Then we will continue in working groups and have the Annual General Meeting of SAG Baumstatik in the afternoon at 2 pm.
