The objective of this project is to improve current knowledge on the effect of wind around bluff objects of circular cross-section at high Reynolds numbers. The work includes: 1) measurements of strains, displacements, accelerations and pressures experienced under wind loads by the 300 m TV Tower at Shenyang, PRC; 2) the analysis of these measurements; and 3) the use of these results in current physical and mathematical models used in estimating wind effects on structures with circular cross-section. The results of this project will benefit the design and construction practices of tall, slender structures subjected to strong wind loading. This project is jointly sponsored by NSF and the Chinese State Education Commission under the 1980 Protocol on Cooperation in Basic Sciences.

该项目的目标是提高当前对高雷诺数圆形横截面陡峭物体周围风的影响的知识。 工作内容包括： 1) 测量中国沉阳 300 m 电视塔在风荷载作用下所经历的应变、位移、加速度和压力； 2) 对这些测量结果的分析； 3）将这些结果应用于当前用于估计风对圆形横截面结构的影响的物理和数学模型。 该项目的成果将有利于承受强风荷载的高而细长结构的设计和施工实践。 该项目由 NSF 和中国国家教委根据 1980 年基础科学合作议定书共同资助。
