Abstract

ABSTRACTThe design and construction of tall, slender steel structures always presents a challenge. This paper presents design aspects (structural system information, analysis methods, applied loads and cost optimisation) and a case study relating to the design and construction of tall windbreak panels 10 m in height. These windbreak panels were constructed in a Greek electricity‐producing industry in order to reduce wind turbulence and improve the performance of its Air Cooled Condenser (ACC). The steel columns were constructed from hot‐rolled IPE 360 cross sections with a height of 10 m, supported by cables in the wind direction and bracing systems in the transverse direction. Concrete anchorages for the cables and concrete footings for the steel columns were used. System optimisation in terms of the steel weight, cable weight and overall costs is discussed and practical issues are explained in terms of technical decisions. Furthermore, construction details, construction methods and cost estimation are discussed.
