摘要：

The　cyclic　tests　are　performed　in　order　to　compare　the　seismic　behavior　of　two　1/6　scale　composite　core　walls　with　different　columns,　one　with　concrete　filled　steel　tube　columns　and　the　other　with　steel　tube-reinforced　concrete　columns.　Based　on　the　experiment,　load-carrying　capacity,　ductility,　hysteretic　property,　stiffness　and　degradation,　energy　dissipation　and　damage　characteristics　of　the　two　specimens　are　compared.　It　is　shown　that　the　seismic　behavior　of　the　core　walls　with　steel　tube-reinforced　concrete　columns　is　better　than　those　with　concrete　filled　steel　tube　columns.　The　mechanical　model　for　calculating　load-carrying　capacity　of　the　new　RC　composite　core　walls　is　proposed.　And　the　calculating　results　agreed　well　with　the　results　from　the　experiments.
