Abstract

In recent years, the process of urbanization in my country has accelerated, the density of buildings in large cities has been increasing, and the height of buildings has also increased, resulting in an increasingly complex wind environment in the city center. An accurate and reasonable description of the characteristics of the wind field within the height of the atmospheric boundary layer in the city center is very important for determining the wind load of the high-rise building structure. This paper uses Windcube 100S Doppler laser wind measurement radar, taking Shanghai as an example, to carry out long-term actual measurement of good wind in the height range of 50m~1200m above Tongji University Wind Engineering Hall and obtain specific and detailed observation data. The time history of wind speed and direction in July and December 2019 is analyzed, and the average wind speed profile and average wind direction profile classified by incoming direction are studied, and the variation law of ground roughness index is obtained. The results show that there is no significant difference in the ground roughness index between different wind directions and seasons. The fitting values of ground roughness index in different directions for heights below 250m are greater than corresponding values for heights above 250m in the same direction, and are greater than the load specification values under class D landforms.
