A　finite　element　analysis　(FEA)　model　was　presented　in　this　paper　to　study　the　seismic　behaviour　of　concrete-filled　steel　tubular　(CFST)　frame　to　reinforced　concrete　(RC)　shearing　wall　high-rise　mixed　structures.　Two　shaking　table　model　tests　on　CFST　frame　to　RC　shearing　wall　building　system　were　carried　out　to　verify　the　theoretical　model.　The　building　considered　in　this　study　had　20　CFST　columns　and　typical　RC　shearing　walls.　The　test　parameters　included　the　frame　column　cross-sectional　type　and　the　peak　acceleration.　The　FEA　models　were　then　used　to　analyze　the　mode　shapes　and　time-history　responses　of　the　mixed　building　structures.　The　calculated　results　were　compared　with　the　experimental　results.　Finally,　some　suggestions,　which　maybe　references　for　the　seismic　design　of　the　mixed　building　structures,　were　presented.
