Abstract: A bridging device in center girder construction for a building joint between two building components having at least two edge girders and at least one center girder arranged between the edge girders and on at least one cross member bridging the building joint that each have a cross member bearing for bearing the cross member on the respective building components at their lateral ends. The object of the present invention is to provide a novel bridging device that is formed in particular space-saving. The initially described bridging device has a cross member having at least two cross member segments arranged along a longitudinal axis of the cross member and arranged displaceable relative to each other toward the longitudinal axis, so the length of the cross member is variable.

Abstract: An energy dissipating device which is capable of dissipating energy through its plastic axial deformation without undergoing buckling comprises at least three hysteretic elements, being interconnected in series in such a way, that at least one hysteretic element will be subjected to compression while at least another hysteretic element is subjected to tension when an external load is applied to the energy dissipating device.

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.
