e.g.: open landscape, hilly: Dropdown field for other tree species
Describes “wind retardation due to topographic conditions at the tree’s habitat. Other = manual input
English oak:Dropdown field for other tree species
Parameters for the tree species. (Stuttgarter Festigkeitskatalog./elasticity benchmark in %, cw value)
Other = manual input
Gust coefficient: Increase of wind velocity due to tree periphery situations, e.g. urban canyons (max. 1.4, up to 1.8 in exceptional cases)
Frequency coefficient: Resonance vibrations of the tree, e.g. Serbian Spruce, max. 1.4, broadleaf trees usually not exceeding 1.2
Top surface: Value obtained from top surface program
Anchoring point distance: Distance of attachment point of the tree to anchoring attachment point
Atmospheric pressure: Usually 1000mb
Temperature: Usually 10°
Load centre: Surface centre of gravity from top surface program
Equivalent load / height: Height of attachment of pull rope at the tree

Theoretical stability of an assumed remaining wall in a certain height

Set height: Height of the trunk cross section to be calculated from: mean trunk diameter and mean decay diameter

Input of measured values

Tensile load: Individual load values of respective load steps
Inclination: the inclination of the root plate
Percentage of breakdown: After filling in the inclination TSE calculates the percentage of breakdown. You can edit this value if you want after you activate the Button “editable”
SNr.: Strain sensor number
SL: Corresponding strain sensor length (in mm).
distension: Strain sensor’s measuring value of the respective load step (given in 1/1000mm).

Interim values

Load crown: Wind load at the top surface centre
Theoretically moment dummy load anchor point: Force to be used to pull on the tree at the load introduction point in order to simulate the wind load at the top surface centre
Vreal²/Vreal: assumed wind velocity in m/s resulting in the assumed wind load at the top surface centre (the following are considered: terrain – gusts -frequency – cw value, atmospheric pressure and temperature)
Real force: Corrected value for the diagonal pull
Theoretically falling force dummy load point: Theoretical tilting load at the load introduction point for the respective load step
Theoretically falling moment trunk base: Theoretical tilting moment at the trunk base for the respective load step

After entering all data click the button “Calculate”.
The relevant safety values in relation to the values obtained (tilting angle and strain sensors) are displayed in the blue result fields.
Safety value to aim for: 1.5
