Quasi-static　tests　of　two　2-story　structures　reinforced　with　HRB　600　MPa　reinforcement　and　ultrahigh-strength　(UHS)　reinforcement　were　conducted.　These　two　structures　showed　an　evident　post-yield　stiffness,　which　can　be　repaired　before　a　large　drift　ratio　of　2%.　The　structure　with　the　UHS　reinforcement　had　stable　floor　stiffness　ratio,　which　can　avoid　the　deformation　and　energy　consumption　concentration　in　the　lower　floors.　The　reinforcement　diagonal　bracing　can　effectively　limit　the　inclined　crack　development,　and　reduce　the　shear　strength　degradation　of　the　shear　wall　under　large　lateral　deformation.　According　to　the　structure　failure　mechanism,　an　ideal　load-deformation　response　was　proposed.
