摘要：

In　order　to　ascertain　the　dynamic　performance　of　the　low-rise　recycled　aggregate　concrete　(RAC)　shear　wall　with　concealed　bracings,　the　shaking　table　tests　of　three　RC　shear　wall　models,　including　a　natural　aggregate　concrete　shear　wall　and　two　RAC　shear　walls　with　or　without　concealed　bracings,　were　carried　out.　The　natural　frequency,　dynamic　response　of　acceleration,　response　of　displacement,　as　well　as　the　failure　patterns　of　three　models　at　different　loading　stages　were　measured　and　compared　on　the　basis　of　the　tests.　The　finite　element　nonlinear　time-history　response　analysis　was　also　conducted,　and　the　analysis　results　agreed　well　with　the　experimental　results.　The　results　show　that　the　natural　frequency　of　low-rise　RAC　shear　walls　is　slightly　lower　than　that　of　the　natural　aggregate　concrete　shear　wall.　The　aseismic　capacity　of　RAC　shear　wall　is　able　to　achieve　the　level　as　the　natural　aggregate　concrete　shear　wall　by　setting　up　concealed　bracings　inside　the　wall.
