Wind Tunnel Investigation of Twisted Wind Effect on a Typical Super-Tall Building
نویسندگان
چکیده
This paper investigates the twisted wind effect on a typical super-tall building (500-m-tall square prism) by conducting pressure model tunnel tests. Two fields (TWFs) with maximum yaw angles of approximately 30° and 20°, respectively, near ground level were generated in using guide vane system, test results load TWFs compared those obtained conventional (CWFs) constant direction along vertical axis. In particular, distribution extreme cladding as well correlation coherence local loads are discussed detail. It was observed that mechanism structural dynamic responses, such vortex shedding, is greatly affected TWFs. Both distributions mean pressures significantly differ from CWFs, especially windward side facades. However, terms amplitudes, do not noticeably exceed CWFs. study aims to provide useful information for wind-resistant design future tall buildings.

Wind 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 کاملAn Investigation on Performance of Shrouding a Small Wind Turbine with a Simple Ring in a Wind Tunnel
Ducted wind turbines are a kind of small wind turbine having a diffuser or any other shape around the rotor which increases the air flow through the blades and absorbs more power. In the present study, a small wind turbine was ducted with a relatively simple ring and its performance was investigated in a wind tunnel. The duct is shaped using rolling steel sheets on a sloping surface and finally...
