As　a　no-disturbance　integrated-retrofitting　technique,　an　external　rocking　frame　was　widely　used　on　reinforced　concrete　(RC)　structures.　Yet,　with　the　increasing　demand　for　seismic　strengthening　of　existing　buildings,　it　has　become　a　concern　to　evaluate　the　seismic　strengthening　schemes　based　on　seismic　resilience.　Firstly,　the　dynamic　equation　of　the　structural　system　was　derived,　and　the　deformation　control　mechanism　was　revealed;　thus,　the　corresponding　design　method　was　put　forward　for　the　rocking　frame　reinforcement.　Secondly,　after　soft-first-floor　structures　were　reinforced　by　rocking　frames,　the　evaluation　method　of　the　reinforcement　scheme　was　investigated　based　on　seismic　resilience.　Finally,　the　feasibility　of　the　assessment　method　was　verified　by　a　soft-first-floor　frame　structure,　and　a　comparison　was　made　between　the　method　proposed　in　this　paper　and　the　conventional　method.　The　results　find　that　the　soft-first-floor　structure　reinforced　by　the　rocking　frame　increased　by　10%　in　the　inter-layer　displacement　and　improved　by　55.6%　and　63.0%　in　the　injury　and　mortality　rates,　compared　to　the　buckling-restrained　brace　scheme.　This　indicates　that　the　reinforcement　scheme　of　soft　layer　structures　with　rocking　frames　is　feasible　and　effective,　and　the　reinforcement　evaluation　method　proposed　in　this　paper　can　quantitatively　reflect　the　improvement　in　seismic　performance.
