Numerical Simulation of Interference Effect on Dynamic Wind Loading of Tall Buildings in Close Proximity by Large-eddy Simulation
We attempt to compute the dynamic wind loads on tall buildings in close proximity with large-eddy simulation. Computation is attempted on two building geometries on which strong interference effects have been reported in previous wind tunnel studies. The computation uses a commercial code and a simple model of turbulence characteristics of the incident wind flow. The computed along-wind and acr...
متن کاملAerodynamic Loads on Tall Buildings: Interactive Database
Under the action of wind, tall buildings oscillate simultaneously in the alongwind, acrosswind, and torsional directions. While the alongwind loads have been successfully treated using quasi-steady and strip theories in terms of gust loading factors, the acrosswind and torsional loads cannot be treated in this manner, since these loads cannot be related in a straightforward manner to the fluctu...
متن کاملAerodynamic Admittance Function of Tall Buildings
The aerodynamic admittance function (AAF) has been widely invoked to relate wind pressures on building surfaces to the oncoming wind velocity. In current practice, strip and quasi-steady theories are generally employed in formulating wind effects in the along-wind direction. These theories permit the representation of the wind pressures on building surfaces in terms of the oncoming wind velocit...
متن کاملWind Interference Effect on Tall Building
When a building is located in an urban area, it is exposed to a wind of different characteristics then wind over an open terrain. This is development of turbulent wake region behind an upstream building. The interaction with upstream building can produce significant changes in the response of the tall building. Here, in this paper, an attempt has been made to study wind induced interference eff...
متن کاملInterference effects of wind loads on a row of tall buildings
ABSTRACT: We apply CFD to visualize wind flow around a row of three square-plan tall buildings closely arranged in a row. Increase in wind load on the upwind building is observed when wind blows to the row at 30. CFD results show that the interference mechanism is mainly due by strong channeling of wind flow through the building gaps. This leads to highly negative pressures on building walls fa...
