Field Experiments for Wind Pressures

将进行现场实验，以促进对建筑物表面风压的了解。该项目的目标是：(1)获取建筑物内外压力的可靠数据基础；(2)评估风向波动对风压的影响；(3)验证现有风洞模型和分析模型。现场测试将在德克萨斯州的Lubbock进行，那里经常存在大风条件；待测建筑为位于开阔、平坦、畅通地形上的普通商业建筑；风速和风向，在几个高度，将与压力同时测量，使用自动化仪器建筑和100英尺的塔。第一年的研究活动将集中于建立设施、校准仪器和检查数据采集系统。第二年将致力于建立数据库，分析它，并与风洞数据进行比较。在第三年的实地研究中，建筑将被旋转，以便为风提供另一个攻角。

Field experiments will be conducted to advance the understanding of wind pressures of building surfaces. The objectives of this project are (1) to acquire a reliable data base on external and internal pressures on and in buildings; (2) to assess the effects of wind direction fluctuations on wind pressures, and (3) to validate available wind tunnel and analytical models. The firld tests will be conducted in Lubbock, TX, where frequent high wind conditions exist; the building to be tested is an ordinary commercial structure placed in an open, flat, and unobstructed terrain; wind speeds and directions, at several height levels, will be measured simultaneously with pressures, using the automated instrumented building together with 100 ft. tower. The first year of research activities will concentrate on establishing the facility, calibrating instruments, and checking the data-adquisition system. The second year will be devoted to build the data base, analyze it, and compare with wind tunnel data. A third year of field studies, in which the building would be rotated so as to offer another angle of atack to wind may be pursured.
