The 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.

“…Much more recently, Lopez et al [40] developed more advanced models that allow to estimate K p from the two-dimensional porosity and the diameter of the threads; and Y from the diameter of the threads and the diameter of the inner circumference of the pore. Wind tunnel measurements and CFD numerical modelling has been also a support in other investigations to achieve better characterisations [43] or to identify key parameters (pressure loss coefficient, drag coefficient and tunnel experiments [44].…”

“…Packwood [1] et al Demonstrated the applicability of the numerical simulation method in the calculation of porous windbreak by comparing the simulation of wind tunnel tests and CFD. Davide AL Lori [2] et al Studied the wind-resistant performance of the windbreaks by wind-tunnel tests using a scaled-down model. Dong Xiang-ting [3] et al used numerical simulation method studying the influence of windbreak on the safety of trains under cross-wind, proving that reasonable windbreak design can obviously improve the running safety of trains.…”

The single and double layers porous windbreaks were taken as research subjects for their effects of wind resistance, stability and structural optimization designing. The distribution of static pressure and velocity were researched in both sides of the windbreak. The force and overturning moment were calculated. The characteristics of energy dissipation was compared between the two windbreaks. The aperture ratio, port closing and panel spacing of the double windbreaks were researched. The results show that the kinetic energy was converted to pressure energy and the direction was changed by single windbreak. The votexs were formed near the double windbreak at the same time. The aerodynamic loads of single panel were greatly reduced by double windbreak. The force was more evenly through changing the aperture ratio. Closing the ports and reducing the spacing of the panel both can improve the loads of the double windbreak.
