Abstract: The recently-completed Shenyang radio and television tower provides a unique opportunity to obtain comprehensive measurements of the along-span variation and coherence of wind-induced forces acting on a structure with a circular cross section and along-span variation of body diameter (cylinder flare). This collaborative effort with the Chinese Ministry of Radio and T.V. Design involves several types of sensors and a computer-based data-acquisition system. Measurements include wind speed and direction, surface pressures, and accelerations in the slipformed reinforced concrete structure. The paper includes a detailed description of the tower structure, the results of an ambient vibration survey and the use of this information in the design and installation of the measurement system.
