| Summary: | To improve stability and deformability of shear panel dampers（ SPD） in the large plastic strain range,issues the optimization of an SPD which was attempted to use the response surface method and verified by tests.SPD with different widths and thicknesses were primarily analyzed by the finite element method（ FEM）,and the strain concentration factor was selected as the optimization target.Optimal parameters were obtained for the SPD when the iterative calculation is converged.According to the experimental results,the optimized damper based on the response surface method exhibits simultaneously a good stability and perfect deformability.This paper provides an effective method for the optimal design of the structure in the large plastic deformation range.
