“…As we progress through the 21 st century, the 4.0-MW and 8.0-MW turbine are on the horizon, along with towers exceeding 100 meters in height. Lewin (2010) stated in his study that an increase of turbine elevation from 80 m to 100 m would result in 4.6% higher wind speed and 14% increase in power output, and an increase from 80 m to 120 m would result in 8.5% greater wind speed and 28% increase in power production. Hence, a logical costeffective solution to increase wind energy production is to build taller wind turbine towers to access higher wind velocities.…”

Wind turbines play a vital role in producing sustainable and clean energy to fulfill the growing energy needs. Energy generated from wind turbines being more sustainable and cost effective, many countries have taken a major step to develop wind turbines with large capacity. There has been a significant reduction in the levelized cost of energy (LCOE) since the 1980's from the development of larger wind farms and from consistent performance improvements of wind turbine components. The power generation capacity I would also like to thank my committee members Dr. Ronald D. Andrus and Dr. Qiushi Chen for their support and taking time to review my thesis. The classes that I took with them were very helpful to develop better understanding of various engineering problems and complete my research. This research was supported in part by the Aniket Shrikhande Memorial Assistantship fund. The financial support of the Shrikhande family is gratefully acknowledged. I would like to convey great appreciation to the Glenn Department of Civil Engineering for providing me with this assistantship. I would also like to thank WPC, A Terracon Company at North Charleston, South Carolina for providing the necessary data which are used in this study. I am grateful to my friends for finding some time to proofread my manuscript. I would like to thank all the staffs, faculties and friends for making my study and stay at Clemson University smooth and enjoyable. vii

“…Aynı şekilde rüzgar türbini kulesi inşaatlarında da bu sistem kullanılmaktadır. Kule yükseklikleri artan diğer türbin kulelerindeki rezonans eğilimi, betonarme kulelerin tasarımına yol açar (Harte, Gideon ve Zijl, 2007;Lewin, 2010). Bu tür kulelerin en büyük avantajı, yerel burkulmanın önlenmesidir.…”

ÖzYenilenebilir enerjinin öneminin daha fazla ön plana çıktığı 21. yüzyılda, en büyük doğal enerji kaynaklarından birisi de hiç kuşkusuz rüzgar enerjisidir. Rüzgar enerjisi için büyük boyutlarda rüzgar tribünlerine ihtiyaç vardır. Bazı durumlarda ise daha küçük ihtiyaçları gidermek için 10m boyutlarında tribün kuleleri kullanılabilmektedir. Bu kuleler çelik, hibrit, betonarme gibi çok farklı şekilde yapılardan oluşabilmektedir. Bu çalışma kapsamında üç farklı tip rüzgâr türbini kulelerinin Bulanık Analitik Hiyerarşi Süreci (BAHS) yöntemiyle seçimi üzerine bir probleme değinilmiştir. Kurulum ve bakım maliyetlerinin yanı sıra ekonomik ömrü sonundaki geri dönüşüm oranları gibi kriterler bu çalışmada dikkate alınmıştır. Bu kriterlere göre farklı en uygun rüzgar tribünü BAHS metodu ile analiz edilmiş ve en uygun kule tipinin seçimi yapılmıştır. Çalışma sonucunda gerek geri dönüşüm, bakım işletme ve montaj kolaylığı gerekse deplasman ve gerilme değerleri bakımından hibrit tipi kule ön plana çıkmıştır.

“…They used finite element method to investigate its structural responses under static and fatigue loads. They stated that the majority of loads on the tower are the wind forces acting on the rotational area of the wind turbine blades, and the moments resulting from the non-uniform wind speed [11][12][13][14][15][16].…”

Wind energy is one of the most economical and clean energy sources in the world. Investments in wind energy are getting increase. Besides, the construction of huge-sized wind turbine towers can result in high costs. The safety in terms of stress and displacement values are also significant for a selected type of turbine towers along with cost. In the design of a wind turbine, the dynamic loads such as wind and earthquake which influence on the tower are also significant. In this regard, dynamic analyses performed for the selection of a wind turbine tower type enable a convenient optimization. In this research, three different towers which have 10 m high were designed. These towers with calculated wind forces and, the recorded acceleration data of earthquakes took place in Chi-Chi, Düzce and Kobe were analyzed using ABAQUS software calculating based on finite element method. The results show that the highest tensile and displacement values were obtained from steel tower type. In terms of stress and displacement values, the most suitable tower type was the hybrid tower.
