Field Measurement of Normal Incident Wind and Wind-induced Response of a Rectangular High-rise Building
摘要
Abstract
This paper presents some selected results obtained from the field measurements of wind effects with the oncoming flow perpendicular to the facade of a rectangular high-rise residential building located in Fushun. Synchronous data of roof-top wind velocities, windward pressures, and acceleration responses are recorded by a three-dimensional ultrasonic anemometer, a low frequency microphone, and two accelerometers respectively. The measured data is analyzed to obtain the information of wind characteristics and wind-induced response of the structure. Statistical analysis of longitudinal fluctuating wind velocities and windward fluctuating pressures shows that they don't obey the normal distribution and exhibit different deviation trends and degrees. The windward fluctuating wind-velocity spectrum of the roof-top of the building agrees well with the von Karman spectrum. For the 80-meter-high rectangular building in the condition of normal wind velocity, the quasi-steady assumption is still appropriate in the windward surface stagnation zone at the relative height of 0.8 and in the analysis of the fluctuating wind pressure and wind velocity. In addition, by comparing the data measured in spring and autumn, it is also found that the wind turbulence is stronger in autumn than that in spring despite that the data in the two seasons are obtained in similar weather conditions and wind force levels. Moreover, the acceleration response data along the two principal directions of the building reveals the torsional vibration phenomena of the building.关键词
