U.S.-China Cooperative Research (Civil Engr.): Measurement of Wind Effects on 300m TV Tower

该项目的目的是提高目前对高雷诺数圆形横截面钝体周围风的影响的认识。工作内容包括：1)中国沈阳300米电视塔在风荷载作用下的应变、位移、加速度和压力测量；2)测量结果的分析；3)将这些结果应用于当前的物理和数学模型中，用于估计风对圆形截面结构的影响。本项目的研究成果将对高、细长结构在强风荷载作用下的设计和施工实践具有借鉴意义。本项目由美国国家科学基金会和中国国家教委根据1980年基础科学合作议定书共同资助。

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.
