Abstract

Nonlinear dynamic time history analysis was conducted for structures with viscoelastic dampers under seismic action in a high intensity earthquake region. The concept of displacement damping region of damper-added structures was proposed, and the damping effect of damper-added structures was evaluated using the inter-story displacement damping ratio. Mass-point systems’ models with different heights were established to perform seismic response analysis of structures, the effects of damper’s parameters and its position on structures’ inter-story displacement damping region were studied. The formula for predicting damping region was proposed through curve-fitting of the inter-story displacement damping ratio. The fitted function was verified with practical engineering cases. The study showed that the damping effect of viscoelastic damper on the structure’s upper part above the layer with damper added is more significant than that on the structure’s lower part below the layer with damper added; damper’s parameters and damping ratios of different layers with damper added have the feature of linear superposition; the fitted formula of the damping ratio can be used to fast evaluate the damping effect of damper-added structures after their vibration reduction objectives are determined.
