Abstract

During an earthquake, high-rise buildings attempt to dissipate energy by generating swaying motion, which causes inevitable building damage. The dampers or passive energy dissipation devices can significantly diminish the energy emitted by earthquakes and reduce building damage accordingly. Especially for high-rise building structures constructed in an earthquake-prone area, it is necessary to install a sufficient number of dampers to reduce the building response. The passive energy dissipation devices present such an optimal performance depends on their locations in the building structures. Therefore, the objective of this paper is to observe an optimal placement configuration of passive energy devices lest excessive installment of the devices. The proposed approach is performance-based optimizations, which seismic performance of buildings considered is story drift of the building. This study focuses on optimizing fluid viscous dampers (FVD) placement incorporated into three-dimensional (3D) regular RC building structure. The result shows that fluid viscous dampers (FVD) when incorporated into three-dimensional of regular RC building structures can modify the performance of the building to fulfill the code standard of allowable drift ratio. It will be then suggested to be prevention acts to improve the performance of high-rise buildings under earthquakes excitation. Hence, the protection of the occupants therein can be accomplished.
