Abstract

This research proposes a technique for reducing the seismic response of a vibration system using TMD and TLD absorbers. Application of the proposed method to the dynamic model of a two DOF shear structure is evaluated. The equation of motion of the system is calculated by considering the nonlinear behavior of the fluid motion inside the TLD container. The nonlinear characteristic of the TLD absorber is modeled using a nonlinear stiffness and dashpot. Robust optimum design of the absorber parameters using Genetic Algorithm (GA) is conducted base on the mean value and the variance of the performance function, which calculated from the ratio between the system response and its excitation signal. The simulation results shown that a combination of TMD and TLD absorbers can effectively reduce the seismic response of a two DOF vibration systems.
