Abstract

<p>To use tuned mass damper (TMD) for structures with period fluctuation, the authors proposed a newly developed semi-actively controlled TMD. Its resonance frequency is controlled by changing the damping coefficient of the variable dampers. This paper reports on its shaking table tests. First, the configuration and control method of the proposed TMD are described. Second, the design concept and specification of the specimen are presented. Finally, the results of the shaking table tests are shown. They are compared with that of simulation analyses, and the accurate operation of the control system and expected behavior of the specimen are confirmed.</p>
