In　this　paper,　reinforced　concrete　core　walls　with　concealed　bracings　is　put　forward　based　on　the　study　of　RC　shear　wall　with　concealed　bracings.　Through　the　contrast　experimental　study　on　one　1/6　scale　normal　reinforced　concrete　core　walls　and　one　1/6　scale　reinforced　concrete　core　walls　with　concealed　bracings　under　the　low　cyclic　loading,　the　effects　of　concealed　bracings　on　the　bearing　capacity,　stiffness,　ductility,　energy　dissipation,　hysteresis　property　and　failure　phenomena　of　reinforced　concrete　core　walls　are　discussed.　The　experiment　shows　that　concealed　bracings　are　able　to　improve　greatly　the　seismic　behavior　of　reinforced　concrete　core　walls.
