摘要：

To　achieve　the　seismic　performance　of　recycled　concrete　shear　walls,　three　1/3　scaled　models　with　different　percentage　of　aggregate　replacement,　including　one　natural　concrete　shear　wall,　one　recycled　concrete　shear　wall　with　100%　recycled　coarse　aggregate　and　one　recycled　concrete　shear　wall　with　100%　recycled　coarse　and　fine　aggregate,　were　tested　on　the　shaking　table.　The　testing　process　included　elastic,　cracking,　and　failure　stages　of　the　model　structures.　Dynamic　characteristic　and　dynamic　response　of　the　structures　at　different　stages　were　studied　and　also　made　the　comparison　between　failure　patterns　of　3　models.　By　comparing　the　test　results　show　that　the　seismic　performance　of　the　recycled　coarse　aggregate　concrete　shear　wall　is　close　to　the　seismic　performance　of　the　natural　concrete　shear　wall.　At　the　first　crack　appearing　on　the　recycled　concrete　shear　wall,　the　peak　of　the　acceleration　applied　to　excite　it　is　decreased　by　9.7%　compared　with　that　applied　to　excite　the　natural　shear　wall.　At　the　failure　stage　of　specimen　with　1/120　roof　drift　angle,　the　peak　of　the　acceleration　applied　to　excite　it　is　decreased　by　5.　8%.　It　can　be　used　to　building　structure　engineering　through　reasonable　design.
