THE DYNAMIC PROPERTIES OF A TUNED LIQUID DAMPER USING AN EQUIVALENT AMPLITUDE DEPENDENT TUNED MASS DAMPER

摘要

In this paper, shaking table tests are conducted to determine the dynamic characteristics ofrna TLD at various excitation amplitudes. The results are used to describe the TLD as an equivalentrnamplitude dependent tuned mass damper (TMD). This model is obtained by maintaining energyrndissipation equivalence. The amplitude dependent TMD model allows the use of existing mathematicalrntools to describe the response of a structure-TLD system. As the effects of a TMD on a structure are wellrnunderstood, the developed model also provides insight into the performance of a TLD. Forced vibrationrntests are conducted on a structure-TLD system to verify the numerical model. Results indicate that anrnamplitude dependent TMD model can correctly simulate the response of a structure-TLD system.
