<p>The present invention concerns an anti-seismic support for supporting a construction engineering structure, which comprises a support (14) having a concave sliding surface (17) and a sliding block (16) with a convex sliding surface (16d) in sliding contact with the concave sliding surface (17), the sliding block (16) being capable of sliding with pendulum motion relative to the concave surface (17) in response to an earthquake tremor or shock, the device (11) comprising a sliding material (19) between the concave sliding surface (17) and the convex sliding surface (16b), where the friction coefficient between the sliding surfaces (16b, 17) is above 10% when the device (11) is loaded with a pressure above 30 MPa and the sliding surfaces are caused to slide at a sliding speed of more than 50 mm/s at a temperature of 20° C. or more.</p> |
