Abstract
Wind velocities are measured at three different heights at the Munich television tower (Olympic tower). At 149 m and 220 m four cup anemometers are placed around the concrete cylinder. On top of the building (290 m) in addition to the wind velocity the direction of wind is determined. The wind-induced stresses are simultaneously measured with Carlson stress meters within the concrete shell at a height of 96 m. All data are punched on tapes which can be further processed with a computer. Drag coefficients and the aerodynamic admittance are determined. The power spectral density is calculated from correlation functions. It is shown that wind velocities can be assumed to be approximately normally distributed. On the basis of the statistical cocnept the mean square of stresses occurring at a given level are calculated.
