To　analyze　the　seismic　performance　of　recycled　concrete　frame　structures,　experiments　on　two　1/2.5　scale　two-story　two-bay　recycled　concrete　frames　under　cyclic　loading　action　were　conducted.　One　of　the　specimens　was　made　from　recycled　concrete;　and　the　other　is　made　from　natural　concrete　in　the　first　floor　and　recycled　concrete　in　the　second　floor.　Load-carrying　capacity,　stiffness　and　its　deterioration　process,　hysteretic　loop,　displacement　ductility,　energy　dissipation,　failure　patterns　and　failure　mechanisms　of　the　specimens　are　analyzed　on　the　basis　of　the　experiments.　Studies　show　that　the　load-carrying　capacity　of　the　two　frame　specimens　is　similar,　stiffness　deterioration　processes　are　the　same,　ductility　of　both　the　two　specimens　can　meet　the　seismic　requirements,　and　their　failure　patterns　fit　the　principle　of　＇strong　column　and　weak　beam＇.　Recycled　concrete　can　be　used　in　multi-storey　frame　structures　or　the　top　part　of　high-rise　frame　structures.
