Since the elastic rubber bearing has better deformation and cushioning properties, so there is a certain seismic rubber bearing performance and better shock absorption cushioning effect, but the design of the research on the seismic bearing a late start, it can be said just beginning to cast bearing spherical bearing, particularly the impact of the error on the shear properties and stiffness caused by seismic rubber movable steel ball bearings, by pulling state of durability, fatigue resistance, rubber and steel plate bonding durability, weather resistance, etc. are required rubber protective layer further study of these issues in the future to do a lot of work further. Currently, depending on the type of classification, rubber bearings can be summarized as laminated rubber bearing, shock absorption and isolation bearing (LRB) and ribbon rubber bearings, bearing the form described by this chapter respectively. Laminated rubber bearings is not a new product, and it is the child in the 1930s started to develop abroad, has been 70 years of history, we can say that a relatively mature product, in foreign countries, rubber engineering authority Mr. E.GKimrnich coefficients of different shapes, different rubber hardness specimens were thousands of times of stress - strain experiments, the first application of laminated rubber bearings on the outskirts of the French Sainfpenis station bridge, to the 1960s ribbon support Block, along with engineering structure will continue to expand, its use will continue to expand the scope and with the progress of science and technology, new materials appear, improvement and development process, the form will not be limited to rubber ribbon bearing travel materials, and other elastomers in the form of universal rotating steel ball bearing hinges, and construction will continue to emerge and develop, so consider using the formula, you should pay attention to new material steel bearings, then the latest structures and new technology products. Bearing steel bearing steel castings or steel processing mainly made in the past, is generally used as a bridge abutment using steel bearing type examination rolling steel parts, swing and slide to accommodate the bridge displacement and rotation. Steel bearing structure according to its use, and there are multiple types of bearing capacity, he is characterized by a strong ability to be able to use a variety of bridge displacement and rotation needs, and the support of the great rebates and a large displacement of the beam and has a very negative rebate good use, before the 1960s, mostly small and medium-span bridges use steel bearings, bearing large tonnage highway bridge now use pot, spherical steel bearing more, but people generally applied steel railway bridge abutment, Commonly used steel bearing has steel bearings and special bearings and so on.
