英文摘要：

Parametric combinatorial optimization of viscoelastic device in earthquake isolation and mitigation of structures is investigated in this paper.Based on the balance between structural performance and construction cost,an objective function for optimization is set up,and a parametric optimization model considering parameters on both material property and shape for viscoelastic device is developed.The genetic algorithms method is used to complete the parametric optimization of a isolation model with single degree of freedom.The numerical results show that the goals of anticipated parametric optimization are achieved when viscoelastic device is installed in structures,and the effective performance of combinatorial optimization by using genetic algorithms is proved.
