Development of large tuned mass damper with stroke control system for seismic upgrading of existing high-rise building

Abstract

This paper describes a large TMD developed as an effective seismic control device for an existing high-rise building. First, we examine the requirements of the TMD using a simple model and clarify the constitution of the actual system. After the control effect through earthquake response analyses is discussed, the results of performance tests conducted on a full-scale TMD system for retrofitting an existing high-rise building are described.
