The present invention is a vibration damping device (1, 2) that includes an external member (11, 21) attached to one of a vibration-generating portion and a vibration-receiving portion; a tubular member (40) attached to the other of the vibration-generating portion and the vibration-receiving portion; and an elastic body (30) which connects the external member (11, 21) and the tubular member (40). The external member (11, 21) includes a frame-like member (11, 21) having a rectangular shape when viewed from the top. In the elastic body (30), a long-side portion (32a) forming a long side of a rectangular shape when viewed from the top adheres to an inner circumferential surface of the long-side portion (12a, 12b) of the frame-like member (11, 21), and a short-side portion (32b) forming a short side of the rectangular shape when viewed from the top comes into contact with the external member (11, 21) in a long-side direction (X) in which the long-side portion (12a, 12b) extends when viewed from the top, in a non-adhering state.

The present invention relates to a construction damper with at least one at least in regions ladder-like constructed thrust damping part which has a spatial structure wherein at least two transverse beams are connected in two different alignments to at least two longitudinal beams and wherein the damping effect is achieved by thrust force damping in the transverse beams.

The present disclosure discloses a radially perforated damper for damping relative movement between a beam and a column. The radially perforated damper comprises at least two radially perforated damping plates, each radially perforated damping plate comprising a central connecting portion configured to rigidly connect to the beam. Each damping plate also comprises a plurality of radial strips extending radially from the central connecting portion such that when an external force is applied to the beam or column, and a moment is applied to the central connecting portion, each radial strip of the plurality of radial strips experiences shear stress and undergoes plastic deformation, thereby damping relative movement between the beam and column.
