Optimal Design Theories of Nonlinear Tuned Mass Damper

The optimal design theory for the linear tuned mass damper(TMD) is well developed, but that for the nonlinear TMD is still developing. In this paper, optimization procedures in time domain are proposed for the design of the TMD with nonlinear viscous damping. The dynamic analysis of a structure implemented with a nonlinear TMD was conducted first. Optimum design parameters for the nonlinear TMD were searched by optimization method such that the performance index is minimized. The feasibility of the proposed optimization method is illustrated numerically by Taipei 101 being implemented with TMD.
