    Abstract: The invention relates to a bearing structure for the damped transmission of impact and/or vibratory forces, in particular for buildings which are subjected to a seismic load, comprising a volume-elastic damping material which is arranged between two parts of a bearing body. According to the invention the first bearing part has essentially the shape of a pot, with a guide sleeve being arranged in the centre of the pot and one or several reinforcing sleeves being arranged between the guide sleeve and the pot inner wall and the damping material filling the spaces between the pot inner wall, reinforcing and guide sleeves at least partially. A second bearing part comprises a bolt which can be displaced inside the guide sleeve, with the bolt being connected with a first fastening plate. A second fastening plate is provided on the outside of the pot in order to anchor the bearing parts at the building.
