Abstract

Abstract

Based on the Davenport wind speed spectrum, the responses of 6-parameter practical viscoelastic damping energy dissipation structures were studied systematically. Firstly, the differential constitutive relation of the 6-parameter viscoelastic damper was used to establish the motion equation of the energy dissipation structure under the Davenport wind spectrum excitation. Then, the motion equation was transformed from the 2nd-order differential equation to the 1st-order one by means of the complex mode method, and the frequency-domain solution and the power spectral density function expression of the energy dissipation structure system under wind excitation were obtained. Finally, based on the random vibration theory, the analytical solutions of the response of the energy dissipation structure system under the Davenport wind spectrum excitation and the force response of the damper, were obtained with the mathematical identity. This method not only contains the results of the all-vibration-mode expansion of the structure system under wind excitation, but also has more simple and efficient expressions than existing methods, and applies to nonclassical structures.
