A　new　combined　steel　lead　damper　(NCSLD)　was　presented.　Construction　and　working　mechanism　of　NCSLD　were　introduced,　pseudo-static　tests　of　the　small　size　dampers　which　would　be　used　in　the　subsequent　shaking　table　tests　were　carried　out　for　the　study　of　mechanical　properties　of　NCSLD　using　electro-hydraulic　servo　press-shear　machine.　Processing　technology　of　the　damper　was　improved.　Shaking　table　tests　under　two-dimensional　excitation　on　structural　aseismic　control　of　a　one-story　structure　model　were　carried　out　using　the　small　size　NCSLD;　parameters　of　the　structure　and　shaking　table　were　also　introduced.　Results　indicate　that　process　improvement　is　beneficial　to　the　implementation　of　working　mechanism　of　the　damper,　NCSLD　has　full　hysteresis　loop　which　takes　on　bilinearity,　NCSLD　has　obvious　energy　dissipation　effect　and　it　can　control　structural　seismic　response　effectively.
