Some innovative concepts use gravity based hybrid constructions. An economically and ecologically promising alternative could be the substitution of the steel tower by a centrically prestressed tower that combines the use of ultra-high performance fibre reinforced concrete (UHPFRC) with the segmental construction method. In this paper the concept of the UHPFRC tower structure is presented. Within the limits of the conceptual design an Eigen frequency analysis was conducted. The results of the analysis were evaluated with respect to the Campbell-Diagram and point to the feasibility of this innovative concept.
