The calculation and design of energy-dissipated seismic retrofit of a 6-story teaching building in a middle school located in seismic fortification intensity of Ⅶ by using viscous fluid dampers is introduced. The structure of the teaching building is the cast-in-situ concrete frame. Considering the using function and seismic performance demand of the building,the teaching building is optimally arranged 52 viscous dampers from the first to the sixth story. The dynamical time history analysis results indicate that the viscous fluid dampers effectively dissipate the energy of structure vibration and obviously reduce the seismic response of the structure.
