Optimal Damper Distribution for Seismic Retrofit by Using A Hybrid GA and A Nonlinear Response Analysis

摘要

1) The minimum damper design satisfying the retrofit target displacement is obtained using the hybrid-GA. Its damper distribution ratio is not affected by the phase difference of the seismic wave on the nonlinear time-history analysis. 2) An existing retrofit design method based on equivalent linearization method is validated by comparing with optimal damper design obtained by hybrid-GA.
