AbstractAnoldofice building with high-riseframe-shear wall structure has been transformed into an elderly care building，and the seismic fortification category has been increased from standard fortification category to key fortification category，and the seismic resistance level of the structure has been increased by one level; Both load and seismic effects have increased in accordance with current regulations.Adopting performancebased seismic design methods，the inter-story displacementratio under rare earthquakes is controled to not exceed the moderate damage limit by adding viscous dampers for energy dissipation and seismic reduction technology reinforcement.The seismic performance of the structure is significantly improved，so reducing the need for seismic structural measures and avoiding large-scale structural reinforcement；At the same time， seismic efects and the reinforcement amount of the main structure have been reduced because viscous dampers provide additional damping.The research results of this study provide reference for retrofit projects with increased seismic fortification requirements.
