Structural health monitoring of the Manitoba Golden Boy

摘要

The study indicates that the range of wind speeds of 59-50 Km/hr produces the maximum strain values of approximately 30 με. This relates to a wind-induced stress of 6 MPa and the combined stress of 94 MPa at the base of the shaft, which are fairly low. The observed value of the fundamental frequency ranges from 3.05 hertz to 2.95 hertz, while the theoretical value is 2.95 Hz. The simplified empirical relationship presented in Fig. 10 is a useful tool to the owner of the structure to get an estimate of the strain in the shaft based on the free-field peak wind velocity.
