THE CONTROL EFFECT ANALYSIS OF HIGH-RISE INDUSTRIAL GAS BUILDING IN THE COMBINED ACTION OF MULTIPLE TUNED MASS DAMPERS AND FLOW VISCOUS DAMPER UNDER EARTHQUAKE ACTIONS

Under the action of earthquake，the vibration of a high-rise industrial gas building is relatively severe． So the study of vibration control under different earthquake action has become more and more important． In this paper，a finite element model of the structure was established，and the modal analysis results showed that torisonal vibration frequency was low and occurred easily． So the torsionsal and bending vibrations of the structure need to be controlled． Therefore，vibration control under interlayer drift，displacement and angle accelerations of top layer was analyzed; and steel support，fluid viscous damper，multiple tuned mass dampers ( MTMD) ，the mixed element of fluid viscous damper and MTMD were installed respectively on the structure，to which seismic loads were applied，which could study the effectiveness of the control effect of the four kinds of measures． The results showed that in most of cases the control effect of the mixed element was better then others．
