The　paper　presents　shaking　table　tests　on　reinforced　concrete　shear　wall　structures　with　and　without　concealed　bracings.　Two　different　models　were　studied　and　the　test　programme　investigated　the　structures　in　the　elastic,　cracking　and　final　failure　stages.　Dynamic　characteristics　and　responses　of　the　structures　at　different　stages　were　determined　experimentally,　and　a　comparison　of　failure　modes　is　presented.　Results　from　the　tests　indicate　that　prior　to　the　concrete　cracking　stage,　the　seismic　performance　of　a　shear　wall　structure　with　concealed　bracings　is　similar　to　that　without　concealed　bracings　(those　without　bracings).　After　the　concrete　starts　cracking,　the　seismic　resistance　of　shear　wall　structures　with　concealed　bracings　is　much　better　than　that　of　those　without　bracings.　The　displacement　response　of　the　shear　wall　structures　with　concealed　bracings　is　much　smaller　than　that　of　those　without　bracings　on　the　ground　floor,　and　the　distribution　area　of　cracks　in　shear　wall　structures　with　concealed　bracing　is　higher　than　that　of　those　without　bracings.
