This　paper　evaluates　the　seismic　performance　of　carbon　fiber　reinforced　polymer　(CFRP)-strengthened　shear　walls　under　various　CFRP　configurations.　A　comprehensive　experimental　investigation　was　conducted　on　five　shear　walls　specimens.　One　specimen　served　as　un-strengthened　reference　specimen,　while　the　remaining　four　were　respectively　strengthened　using　horizontal,　X-shaped,　combined,　and　fully　wrapped　CFRP　strips.　Based　on　the　test　results,　the　effects　of　CFRP　configurations　on　the　failure　modes,　shear　bearing　capacities,　and　deformation　capabilities　were　thoroughly　evaluated.　At　the　same　CFRP　ratio,　the　combined　strip　method　significantly　enhanced　the　shear　bearing　capacity　by　27.8　%　compared　to　the　un-strengthened　specimen.　In　contrast,　the　Xshaped　strip　method　showed　a　limited　increase　in　shear　bearing　capacity　of　6.39　%.　Further　analyses　on　the　strengthening　efficiency　of　different　CFRP　configurations　revealed　that　horizontal　strips　method　exhibited　the　highest　strengthening　efficiency　for　the　shear　strength,　stiffness,　ductility,　and　energy　dissipation,　while　the　Xshaped　method　exhibited　the　least　effectiveness　due　to　early　debonding　of　the　CFRP　strips.　Finally,　the　actual　shear　contribution　of　CFRP　obtained　from　experiments　were　compared　with　the　predicted　values　from　current　standards,　with　the　comparison　results　revealing　an　overestimation　of　the　CFRP　shear　contribution.　To　improve　the　accuracy　of　CFRP　shear　contribution　predictions,　the　effective　strain　reduction　coefficient　capturing　the　effects　of　CFRP　configurations　was　proposed.
