pulling tests, can be compared to the impact of wind dynamics. The standard specifications are preset or available in the libraries. This way, the results of tree static measuring techniques, e. These standards include specifications of dead, wind, maintenance/technician and ice loads (ISO 12494 or DIN 1055-5), as well as variable loads. Following the regulation DIN 1055-4 an equivalent static substitute load is determined which causes the same amplitude like a gusty storm. These phenomena have been scientifically researched on trees during the past years.Īrbostat does provide current scientific results in order to evaluate the dynamic properties of trees. As resonance leads to higher vibration, power tips can be attenuated. Structures subject to vibrations react dynamically in a turbulent wind stream. Moreover, adjustments are made to small-scale airflow conditions, e.g. The impact of urban development and topography on the wind structure is estimated by means of terrain categories based on national standards for aerodynamic engineering. Wind parameters based on standardsĪrbostat follows the calculative approaches of the Eurocode 1. Arbostat provides a comprehensible option for the estimation of expected wind loads. Although they cannot be exactly predicted, such load estimations are indispensible for safety considerations.
