“…The proper selection of the building shape and the introduction of suitable aerodynamic changes may reduce the wind motion or may change its pattern around a building. Therefore, extensive research has been performed on aerodynamic characteristics and the response of the buildings to wind (Amin and Ahuja, 2010;Ilgin and Günel, 2007;Kareem and Tamura, 1996;Kwok and Bailey, 1987;Melbourne and Cheung, 1988;Miyashita, 1993;Xie, 2012) (Figure 2).…”

The study of wind behavior around tall buildings is a critical issue in architectural and structural design. Therefore, Tall modern buildings are extremely sensitive to the wind. Thus, the assessment of wind loads to design these buildings is essential. Monitoring the wind, which is forcing extraordinary tall buildings is highly challenging. By looking at recent constructions in Iran, it is obvious that despite the fact that constructing tall buildings is spreading, there is less concentration on environmental factors such as wind's aerodynamic. The purpose of this study is to introduce a theoretical framework. Hence, by using CFD simulation, investigating on wind speed in various regions of the tall-triangular building have been focused. Finally, Autodesk Flow Design 2014 software is utilized to present a CFD simulation of a building model with a triangular footprint, Rounded Corner aerodynamic correction, and Set-back aerodynamic form. These simulations have been looking forward to finding out about how can aerodynamic forms affect pressure zone reduction in buildings and reduce wind flow pattern in urban regions.

“…It has been proved that modifying the shape of tall buildings can significantly affect cross-wind loads and wind-induced responses (Dutton and Isyumov, 1990;Hayashida and Iwasa, 1990;Kawai, 1998;Kwok, 1988;Kwok and Bailey, 1987;Melbourne, 1989;Melbourne and Cheung, 1988;Miyashita et al, 1993), and hence construction cost. However, an aerodynamically efficient plan shape may come at the cost of usable floor area that, in turn, may require additional compensatory storeys, which obviously increase the wind loads and construction cost again.…”

“…Based on the observed base force, using time or frequency domain analysis, the response of structures can be predicted [8]. Another effective way to evaluate the aeroelastic performance of structures is an aeroelastic test technique [9], [10]. From the HFBB and aeroelastic test, the wind effect on structures could be evaluated and utilized for designing engineering structures.…”

In this paper, the aerodynamic and aeroelastic performance of the bridge tower of the Hong Kong-Zhuhai-Macao Bridge were investigated experimentally. The aerodynamic forces of the bridge tower were evaluated by using five-segment wind tunnel test models. The wind-induced dynamic response of the bridge tower in the alongwind, cross-wind, and torsional directions were tested by using an aeroelastic test model. From the wind tunnel tests, the drag, lift, and torsional force coefficients under different wind attack angles were observed and analysed. The aeroelastic phenomenon (i.e. galloping, vortex shedding) of the irregular bridge tower was evaluated. The most unfavourable case of wind-induced vibrations was analysed and checked. This study provides a way to evaluate aerodynamic and aeroelastic performance of an irregular bridge tower, and advances our understanding of the performance of the bridge tower.
