Application of damping in high-rise buildings

The outrigger structural system has proven to be an efficient lateral stiffness system for high-rise buildings under static loadings. The purpose of this thesis is to research the incorporation of viscous dampers into the outrigger system to improve the dynamic performance. This study will be conducted on a typical high-rise structure in Boston, MA in attempt to find realistic results. This thesis will utilize two analysis models for the study: a simplified single degree of freedom model and a more sophisticated computer model constructed with the structural analysis software, SAP2000. The models will be used to assess the effect that increasing damping or changing damper locations has on the dynamic performance of the structure. Furthermore, the constructability issues of each damping configuration will be identified and discussed.
