RESPONSE CONTROL EFFECT OF HI-RISED STEEL BUILDING STRUCTURE USING TUNED VISCOUS MASS DAMPERS

Abstract

Response control using inertial mass element which gets inertial force due to the relative acceleration is recently studied by many researchers. The authors have proposed a new seismic response control system, the tuned viscous mass damper (TVMD), composed of arranging viscous damping element and inertial mass element which has an apparent mass amplifying mechanism to obtain a large supplemental mass effect in parallel and connecting spring element in series. This paper shows the application of TVMD to a high-rised steel building structure and response control effect of this system.
