Design of assembled post-tensioned prestressed reactive powder concrete wind turbine tower Xinwei Ma1,a, Sen Zeng1,b, Chonghai Dong1,c, Zhi Yu1,d, Guanqi Huang1,e 1Department of Civil Engineering, Harbin Institute of Technology at Weihai, Weihai,264209, China axinwei.ma@163.com, brichard-zen@163.com, cdchlucky@163.com, d408783572@qq.com, e574197520@qq.com Keywords: Reactive Powder Concrete, wind turbine tower, prestressed, design optimization Abstract.This paper proposes a new type of assembled post-tensioned prestressed reactive powder concrete (RPC) turbine tower structure.
The results show that in the same load conditions, the prestressed concrete tower saved 30% of the engineering cost than the steel tower and the fatigue life increased to 40~ 60 years.
