TY  - JOUR
AB  - This paper examines the detailed performance of an Integrated-Damping-System (IDS) approach which wasrecently introduced to provide large damping levels by enabling two parts of a building to move independentlythrough a parallel arrangement of springs and fluid viscous dampers. Extensive assessments into thecharacteristics and distribution of constituent dampers are illustrated through the dynamic response of a typical300m central-core building. Besides examining the system performance under typical wind conditions andselected seismic excitations, five damper placement methods are assessed for various linear and nonlinear damperexponents. It is shown that intermediate exponents provide the best overall response. However, when the designtargets a particular damping, deformation or acceleration related performance parameter, specific combinationsof damper exponent and distribution can result in an optimal application. Most importantly, due to the underlyingIDS nature, which acts as an inherent large-mass damper, the findings show that the overall performance is nothighly sensitive to the damper placement and does not necessitate the use of an advanced distribution. Whilstspecific placements can be adopted to refine targeted performance aspects where necessary, simple and practicaluniform or stiffness proportional arrangements can be consistently employed with the IDS to provide a highlyeffective solution.
