Abstract: Seismic resilience assessment of buildings is a crucial area of research for seismic design. With reference tostandard for seismic resilience assessment of buildings (GB/ T 38591—2020), a seismic resilience assessment program wasdeveloped, which was applied in a primary school building in a high intensity zone. Considering that seismic resilience of buildings is related to the deformation and acceleration response of structures under earthquake, a scheme which combinesbuckling-restraint brace with viscous damping wall was proposed to improve the seismic resilience of the building. Throughthe evaluation of the repair cost, repair time and personnel damage, the seismic resilience level of the building wasassessed. The results show that the developed seismic resilience assessment program is able to realize automatic MonteCarlo extended simulation and seismic resilience assessment. Concrete damage factor and steel strain are suitable damageassessment criteria for the seismic resilience assessment for buildings. The combination of displacement-type dampers andvelocity-type dampers significantly improves the seismic resilience level of the building.

Keywords:seismic resilience assessment;composite damping technique;buckling-restrained brace;viscous damping wall?performance-based seismic design;Monte Carlo simulation method
