Abstract |
|
The application of active multiple tuned mass dampers (AMTMD) for suppressing translational and torsional responses is addressed for a simplified two-degree of freedom structure, able to represent the dynamic characteristics of general asymmetric structures subject to ground motions. By employing the developed optimum parameter and effectiveness criteria of the AMTMD, the influences of the normalized eccentricity ratio and the torsional-to-translational frequency ratio of asymmetric structures on the optimum parameters and effectiveness of the AMTMD are investigated in detail. For comparison purposes, the results of a single active tuned mass damper also are taken into consideration. |
