Abstract: For uncoupling a building structure from the ground a sliding pendulum bearing is suitable for the protection of building structures in the case of movements of the ground, due to earthquakes for example, or as an alternative for conventional deformation bearings. The bearing has a first sliding face with a first concave sliding face and a sliding shoe, which is in sliding contact with the first sliding face of the first sliding plate. A low friction material of a low-friction plastic is entrapped in the sliding shoe which has elastoplastic equilibrium properties. In particular as a low friction material a ultra high molecular weight polyethylene (UHMWPE) or polytetrafluoroethylene (PTFE) is utilized. After a displacement entailed by an external force the sliding shoe returns of its own accord into a stable equilibrium position.

Abstract: For uncoupling a building structure 3 from the ground 2 a sliding pendulum bearing 1 is suitable for the protection of building structures in the case of movements of the ground 2, due to earthquakes for example, or as an alternative for conventional deformation bearings. The bearing 1 has a first sliding face 5 with a first concave sliding face 5? and a sliding shoe 4, which is in sliding contact with the first sliding face 5? of the first sliding plate 5. A low friction material 9a of a low-friction plastic is entrapped in the sliding shoe 4 which has elastoplastic equilibrium properties. In particular as a low friction material 9a ultra high molecular weight polyethylene (UHMWPE) or polytetrafluoroethylene (PTFE) is utilized. After a displacement entailed by an external force the sliding shoe 4 returns of its own accord into a stable equilibrium position.
