Abstract
Research on application of a rotary inertiai damper in a seismic isolated structure has been conducted by many researchers in pursuit of threefold objectives; response control in multiple levels of input ground motions, reduction of floor response accelerations. and establishment of optimum damper design method. The authors propose a new type rotary mertiai damper referred to as a viscoelastically supported viscous mass damper (VeVMD). Unlike a conventional force restricted viscous mass damper (FRVMD), an apparent mass and viscous element arranged in parallel are supported by viscoelastic material to obtain better performance. A set of paxeto-optimum designs ofVeVMD system is sought by a multi-objective genetic algorithm.
