摘要： The seismic isolation sliding support bearing system includes a pair of sliding bearings, which can be moved relatively to each other and are arranged in opposition and in contact with each other between a superstructure and a substructure. At least one of the pair of sliding bearings is a sliding bearing (a) made from a molding, having a porous structure including a plurality of voids, of a composition including PTFE as a main component and aromatic polyester resin, or a composite including a base member having the molding on the surface thereof. Furthermore, a lubricant holding layer for holding a flow lubricant in the voids is formed in a surface portion of the molding. Since the sliding bearing (a) has a high compression elastic modulus (of 900 MPa or more) and a low coefficient of friction (of 0.02 or less) and can maintain the low friction for a long period of time, it can be particularly effectively used in a seismic isolation sliding bearing support system for structures with a large load.
