The　optimal　repair　decisions,　considering　the　damage　degree　of　members　and　the　available　repair　resources,　can　expedite　the　restoration　of　the　seismic　performance　of　seismic-damaged　structures.　This　study　focuses　on　seismic-　damage　structures　and　proposes　a　comprehensive　seismic　performance　loss　calculation　method.　Under　the　condition　of　limited　repair　resources,　to　ensure　that　the　maximum　improvement　of　seismic　performance,　this　study　establishes　the　optimal　repair　strategy　determination　method　based　on　the　greedy-genetic　algorithm.　Further,　an　optimal　repair　sequence　determination　method　is　developed　to　ensure　seismic-damaged　structures　with　good　seismic　resilience,　and　a　recovery　function　model　based　on　the　SIR　(susceptible　infected-recovered)　model　is　proposed.　In　addition,　this　study　introduces　the　structural　seismic　fragility　analysis　method　that　considers　uniform　risk.　A　5-story　reinforced　concrete　structure　is　analyzed　as　an　example.　The　analysis　results　demonstrate　that　the　proposed　optimal　repair　strategy　determination　method　requires　minimal　iterations　to　determine　the　optimal　solution;　Compared　with　random　repair　sequences,　the　optimal　repair　sequence　determination　method　can　enable　the　structure　to　exhibit　better　seismic　resilience;　Distinct　from　the　three　traditional　recovery　function　models,　the　proposed　recovery　function　model　can　adeptly　reveals　the　influence　of　different　repair　sequences　on　the　seismic　resilience　of　structures,　and　has　good　applicability.
