摘要：

In　order　to　investigate　the　flexural　behavior　of　recycled　aggregate　concrete　composite　slab,　the　repeated　load　tests　of　recycled　coarse　aggregate　concrete　and　normal　concrete　composite　slabs　with　closed-section　steel　deck　were　carried　out.　Based　on　the　tests,　the　flexural　behavior　of　recycled　coarse　aggregate　concrete　composite　slabs　with　different　constructional　measures　and　thickness　was　analyzed　and　compared　with　that　of　normal　concrete　composite　slabs.　The　methods　of　calculating　ultimate　moment　and　deflection　of　the　recycled　coarse　aggregate　concrete　composite　slab　with　closed-section　steel　deck　were　advised.　The　results　show　that,　compared　to　normal　concrete　composite　slab,　the　recycled　coarse　aggregate　concrete　composite　slab　has　slightly　smaller　flexural　load-bearing　capacity　and　stiffness.　So,　it　can　be　applied　in　actual　engineering　structures　through　reasonable　designing.　Adding　reinforcement　truss　into　the　recycled　aggregate　concrete　can　obviously　increase　the　flexural　performance　of　composite　slab.
