This load is then included as comparative value in further calculations for stability and safety against fracture. In compliance with the rules of DIN 1055, TSE connects the various influence factors of wind loads on trees and as a result provides a theoretical maximum wind load acting at the load centre. Squall factor (represents the influence of wind-enhancing effects and turbulences, e.g.Terrain factor (includes wind-decelerating topographic conditions, e.g.Frequency factor (considers the oscillation willingness of the tree).Aerodynamic behaviour of the tree top (Cw value).Top sail surface and its load centre (for this, use of an appropriate computer programme, e.g.TSE integrates the following tree-specific and topographic factors for calculation of the expected wind loads: assuming hurricane-like wind conditions) that are applied to the tree is required. For calculation of the stability and safety against fracture of a tree, initial evaluation of the maximum wind loads (i.e. Structural system: Three-field span with equal field lengths L. The wind load that a tree is exposed to has a decisive influence on tree-statistics calculations.
