The natural frequencies of the coupled in-line towers are the most important parameters for dynamic analysis when the designer takes steps to assure that damages due to wind loads, seismic loads, or wind-induced vibration would not occur. In this paper the authors present an analytical method for determining these parameters. The theoretical results are compared with the experimental data obtained from the industrial towers in the field, and are in good agreement.
