Abstract:Parametric optimization of viscoelastic dampers in earthquake isolation and mitigation of structures is investigated in this paper. Based on the energy equation, an objective function for optimization is set up, and a parametric optimization model for viscoelastic dampers is developed. Then, the genetic algorithms method programmed by MATLAB is used to complete the parametric optimization of a cylindrical reticulated shell modeled by ANSYS, and the sensitivity to the earthquake waves of this method is also studied. The parameters of the viscoelastic dampers are obtained by genetic algorithm based on energy equation. The numerical results show that the displacement and stress of the structure are controlled effectively. Additionally, the different earthquake waves have little influence on the results obtained by the method.
