2. Ice and wind loads on guyed masts
Abstract : Atmospheric icing is a large problem for many structures located in regions with cold climate. Structures as guyed masts and overhead transmission lines and towers are particularly exposed. A 323 meter high guyed TV and radio mast in Arvidsjaur in Northern Sweden was equipped with an extensive data collection system in the winter 1988-89. READ MORE

3. Resistance of Circular and Polygonal Steel Towers for Wind Turbines : Down scale component experiments and Finite element analysis
Abstract : With increasing demand of sustainable energy production, the harvesting of wind power by using wind turbines have become increasingly important over the last few decades. Most of the wind turbine towers are made from steel. Towers are an important part of the investment in wind parks and contribute about 20% of costs for the onshore towers. READ MORE

4. Vertical Axis Wind Turbines : Tower Dynamics and Noise
Abstract : Vertical axis wind turbines (VAWTs) have with time been outrivaled by the today common and economically feasible horizontal axis wind turbines (HAWTs). However, VAWTs have several advantages such as the possibility to put the drive train at ground level, lower noise emissions and better scaling behavior which still make them interesting for research.
