Displacement-based Design Method of Supplemental Energy Dissipation Devices for Hi-Tec Factory Buildings

The performance demand of the technology factory buildings(fabs) is higher than the general buildings. One of the design objectives is to restrict the structural displacement under the design earthquake; meanwhile, the story acceleration under the moderate earthquake would also be controlled to conform to the performance objective. The use of passive energy dissipation devices can reduce the response of structures. These devices absorb input energy during an earthquake. The seismic design with energy dissipation devices can be used to the new structural design or to the retrofit design of existing buildings. Several types of energy dissipation devices such as viscoelastic damper, viscous dampers, and yielding type dampers can be used. Various references about the design and application of these dampers reiterate the efficiency of these devices in reducing effectively the seismic effects. Besides, the tuned mass dampers used for tall buildings are necessary to reduce the vibration induced by wind force, and its efficiency to reduce seismic response is also studied in many references. Moreover, this study provides the design procedure to satisfy the performance objectives of using appropriate energy dissipation devices for fabs. The performance objectives in this study are to restrict the structural displacement under the design earthquake to control the story acceleration under a moderate earthquake in satisfying the performance level.
