Evaluation of Dynamic Properties of Trees Subjected to Induced Vibrations

The preservation of trees in urban and archeological areas is a theme particular relevance. Modern systems monitoring, together with approaches for deriving the main characteristics influencing their response toward extreme events, are nowadays at basis growing number studies. aim present paper dynamic identification carried out by employing an approach which combines simple data-acquisition system, direct ambient sources excitation, different data-processing methods. In particular, using single accelerometer placed sections trunk considering excitations induced either pulling tests or vibrations, derivation frequencies levels modal damping characterizing sour cherry tree (Prunus cerasus) out. A finite element model also to support validation proposed further analyze derived outcomes. obtained results underline feasibility information useful assessing behavior actions and, consequently, relevance possible damages variations terms (frequencies) damping.
