The Response Of Wind-induced Vibration And The Equivalent Static Wind Load Of Structures With Viscous And Viscoelastic Dampers

The analytical solution of the equivalent damping rate and the equivalent static design wind load of the energy dissipation structure is obtained. The major work of this thesis is as following:1. The frequency response analysis method is apllied to analyse the frequency response characteristic of the response of the random wind-induce vibration based on Davenport spect- rum of the structure with Maxwell viscous and viscoelastic dampers, and then the analytical solution of the response of the random wind-induce vibration and the equivalent static design wind load is gained.2. The response of the random wind-induce vibration based on Davenport spectrum of the energy dissipation structure with viscous and viscoelastic dampers is researched by the stochastic averaging method. Damper models include general integral model, general differ- ential model and general fractional derivative model. And by the stochastic averaging method and the equivalent criterion of strochastic averaging analysis, the equivalent damping rate of the structure is obtained, which transfered the energy dissipation structures with dampers into ordinary structures.
