The structure damping can be increased and vibration of structure can be suppressed by setting up viscoelastic damper in the frame structure so as to shock absorption.Based on the viscoelastic damper working principle,earthquake response of reinforced concrete frame structure with viscoelastic damper,which was installed in different mode,was analyzed in this paper by use of ETABS finite element software.As a result,we obtained the damping effect of frame structure with viscoelastic damper and established the reasonable arrangement mode.
