Abstract：This paper proposes a simple and practical numerical optimization design method for frame shear structure-TMD system. Frame shear structure is simplified into a continuous cantilever beam with lumped parameter model. This model can not only simulate the structural lateral displacement reasonably, but also consider structural bending deformation.Structural natural vibration characteristics were analyzed by using Rayleigh-Ritz method.Optimal design of TMD based on the genetic algorithm, with the structural performance as optimization objective. The methods applied to the optimum design of a frame shear structure-TMD damping system to reduce seismological response, and its numeral simulation analysis was conducted.The analysis results indicate this TMD numerical optimization method is very effective.
