DERIVATION OF OPTIMAL DESIGN CONDITIONS FOR TMD WITH DYNAMIC MASS AND VERIFICATION BY VIBRATION TESTS

Abstract

This paper derives the optimal design conditions by the relational expression of natural period and propose the design method for the tuned mass damper (TMD) using a rotary inertial mass damper called DTMD. It shows the design example for the multi degree of freedom (MDOF) system, and confirms the damping effect of DTMD by the response analysis. In addition, it verifies the proposed theory and confirms the control effect on the actual structure by the vibration tests.
