EARTHQUAKE RESPONSE CONTROL OF TIMBER STRUCTURE WITH UNBALANCED DISTRIBUTION OF SHEAR WALLS UTILIZING VISCOELASTIC DAMPER : Shaking table test with three-dimensional model and analysis of response mechanism

Abstract

This study is to obtain basic knowledge about application of the damper to timber structure with eccentricity. First the mechanical characteristic and analysis model of the damper are re-evaluated by the shaking table test and comparing previous research. Then seismic response characteristics of timber structure with eccentricity installed Viscoelastic damper in, especially the effect of eccentricity ratio and quantity of the damper on maximum response, are comprehended by the shaking table test with Three-Dimensional model. Based on these experimental studies, it is clarified that the viscoelastic damper works on control of torsional vibration effectively by computer analyzing of seismic response mechanism of Three-Dimensional shear deformation model.
