Analysis of vibration reduction effects for energy dissipation structures with non-linear viscous dampers

In this paper the response spectrum method is applied and improved for predicting the seismic response of energy dissipation structures with non-linear viscous dampers. By comparing the numerical results of the present method with that of the time history method, it is shown that the present method is reasonable. The method has been used to investigate the influences of the brace stiffness and the viscous dampers parameters on vibration reduction effects. After numerical analysis, the rational range of the brace stiffness parameter has been suggested for the best suited values of the displacement reduction ratio. And the design method to select the parameters of viscous dampers has been summarized for getting reasonable values of shear force reduction ratio.
