In the reconstruction of existing buildings,energy dissipation and shock absorption reinforcement technology using the seismic performance-based design can reduce the requirements of seismic measures to improve seismic fortification category of existing buildings.Taking the reconstruct project of a storage building into a medical building in Chongqing as an example,the vibration reduction rates of frequent and rare earthquakes were analyzed by using viscous energy dissipation device,the structural measures were strengthened for the weak position of the through column and the large opening of the floor slab.The analysis results show that the seismic performance-based energy dissipation and damping technology can be effectively controlled and the preset seismic performance target can be achieved.The seismic measures can be designed according to reducing one degree.Through a small amount of reinforcement,not only enhance the safety and applicability of the structure from the whole to the local overall,but also can save time and cost.
