The　material　properties　and　mechanical　properties　of　low　stiffness　rubber　bearings　are　systemically　performed　both　in　test　and　in　theory　in　our　research.　There　are　two　types　of　low　stiffness　rubber　bearings,　natural　rubber　bearings　(NRB)　and　lead　plug　rubber　bearings　(LPRB),　total　18　specifications　and　30　large　diameter　specimens　are　tested　for　grasping　various　properties.　The　characteristics　of　low　stiffness　rubber　bearings　include　fundamental　properties　such　as　vertical　stiffness,　horizontal　stiffness　and　damping;　extreme　properties　such　as　buckling,　extreme　compressive　stress　and　maximum　shear　strain;　various　dependence　such　as　compressive　stress,　shear　strain　and　temperature;　duration　properties　of　aging　and　creeping.　In　this　paper,　various　dependence　of　compressive　stress,　shear　strain　and　temperature　are　studied　for　both　NRB　and　LPRB,　and　aging,　creep　are　tested　too　to　grasp　the　properties　of　low　stiffness　rubber　bearings.　A　modified　formula　for　temperature　and　a　modified　stiffness　and　yield　load　table　are　provided　in　the　end　of　the　paper　for　analyzing　the　earthquake　response.
