The effect of the installation of tuned mass damper(TMD) to reduce building vibration due to wind force has been affirmed. However, the application due to seismic force is still in development. Whether the TMD can achieve the proper effect is dependent on its design parameters, the frequency ratio and TMD damping ratio. For this reason, this article aims to obtain the optimal TMD parameters for the damped structure subjected to the white noise earthquake to minimize the mean square of the structural absolute acceleration. However, for the damped structure, the closed-form solution of the optimal design parameters cannot be obtained. Therefore, an iteration method to solve two nonlinear equations for the optimal design parameters is proposed. |
