Abstract
Provided is a high-performance sliding seismic isolation device with a slider that realizes a contact pressure of 60 MPa. The device includes an upper shoeand a lower shoe () having sliding surfacesandwith curvatures, respectively; and a columnar steel slider () disposed between the upper shoe () and the lower shoe (), the slider having an upper surfaceand a lower surfacethat are in contact with the upper and lower shoes, respectively, and have curvatures. The upper surfaceand the lower surfaceof the slider () have double-woven fabric layers () and (), respectively, each double-woven fabric layer containing PTFE fibers and fibers with higher tensile strength than that of the PTFE fibers, and the PTFE fibers being arranged on the sides of the sliding surfacesandof the upper shoe () and the lower shoe ().
