This paper presents the process of making a set of vibration measurements on a model of a television tower in the boundary layer wind tunnel. The main objective of the study is to predict the dynamic behaviour of the full-scale structure under the turbulent wind action, specific for the Bucharest site, in Romania. Wind tunnel tests were performed on a 1:500 scale aeroelastic model, existing at the Aerodynamics and Wind Engineering Laboratory “Constantin Iamandi” from the Technical University of Civil Engineering Bucharest. As a result of the vibration measurements on the tower's model, the dynamic behaviour of the structure on the real scale could be determined by using the conditions and relationships of similitude established between the two, model and prototype (full-scale structure). The experimental analysis made in this study may be very important not only in assessing the dynamic response for a building of such importance, during the preliminary stages, but also can be very helpful for the decision makers involved in the design process to choose which is the best solution for such high and slender structures under the action of turbulent wind.

After decades of development, one of the most mature renewable energy technologies is recognized to be wind energy. Compared to other renewable energy sources the wind potential that can be used to produce electricity is much higher. Currently, the conversion of wind energy into electricity has several advantages, among which can be mentioned the following: “clean” energy source, renewable energy source, low costs per unit of electricity produced. Thus, the progress of future technological innovations must lead to the achievement of wind turbines that are more efficient, more robust, and less expensive than actual technology. The aim of this work is to provide an overview of the Global, European and, especially, Romanian situation of the wind energy market. Moreover, are presented aspects related to innovative constructive solutions for wind turbines used to capture wind energy in areas where wind potential is low.

The presented paper focuses on the computation of the mean wind speed and turbulence intensity profiles for all the cities from Romania. The calculation of both, the mean wind speed profile and the turbulence intensity profile, had as mathematical support the equations presented in the Romanian design standard for wind action CR 1-1-4/2012. The main objective of this paper was to provide a tool for the computation of the two wind action features. This method was based on creating a spreadsheet in Excel with which, in just a few seconds, a user could correctly obtain the two wind characteristics. This Excel dashboard can be used as a teaching material for students as well as input data for structural design engineers in the process of modelling and observing the behaviour of a building excited by wind action on a particular city in Romania.
