EFFECTIVE DAMPER DEFORMATION RATIO OF OPTIMAL DAMPER SHEAR COEFFICIENT FOR HIGH-RISE BUILDING WITH HYSTERETIC DAMPERS

Abstract

The placement and number of passive dampers employed in building greatly affect the response reduction, thus, must be considered in designing. In the previous study considering only one damper layout plan and constant damper ductility demand, the effective damper deformation ratio of optimal shear coefficient to be the median value was confirmed. In this paper, several damper layout plans and different damper ductility are considered, and the effective damper deformation ratio of optimal shear coefficient and of maximum equivalent damping ratio in order to clarify the relationship between the effective damper deformation ratio and damper ductility demand are compared.
