Anti-seismic support

The invention concerns an anti-seismic support for supporting a construction engineering structure, which comprises a support having a concave sliding surface and a sliding block with a convex sliding surface in sliding contact with the concave sliding surface, the sliding block being capable of sliding with pendulum motion relative to the concave surface in response to an earthquake tremor or shock, the device comprising a sliding material between the concave sliding surface and the convex sliding surface where the friction coefficient between the sliding surfaces is above 10% when the device 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
