| Abstract: | The material properties, mainly including mechanical properties, of low stiffness rubber bearings are systemically studied both in test and in theory in our research. There are two types of low stiffness rubber bearings, natural rubber bearings and lead plug rubber bearings, total 18 specifications and 30 large diameter specimens are tested.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 extreme shear strain; various dependence such as compressive stress, shear strain and temperature; duration properties of aging and creeping. The mechanical characteristics, including vertical stiffness, horizontal stiffness and damping, of low stiffness rubber bearings are published in this paper firstly, the other tests and properties will be published later. |
