The design and construction of tall and slender steel structures is always\nchallenging. This paper discusses several design aspects (structural information,\nanalysis methods, applied loads, cost optimisation) and a case study regarding\nthe design and construction of 10-m-tall windbreak panels for a\nGreek electricity producer. The purpose of the panels is to reduce wind turbulence\nand improve the performance of the electricity producerâ??s air-cooled\ncondenser. In this case, the main wind load acts in the longitudinal direction,\nwith friction inducing only a small amount of wind load in the transverse direction.\nThe steel columns are constructed from 10-m-tall hot-rolled IPE 270\n(S235) cross-sections, and are supported by cables in the longitudinal direction\nand bracing systems in the transverse direction. Concrete anchorages\nand concrete footings are used for the cables and steel columns, respectively.\nSystem optimisation is investigated in terms of the steel weight, cable length,\nand overall cost, and practical issues are explained regarding technical decisions.\nFurthermore, the construction details, construction methods, and cost\nestimation are discussed.
