Abstract
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.
Claims9
A damped structure comprising:
- a beam;
- a column;
- a radially perforated damper comprising at least two radially perforated damping plates, each radially perforated damping plate comprising:
- a central connecting portion rigidly connected to the beam;
- a continuous perimeter rigidly connected to the column;
- a plurality of radially elongated strips extending radially from the central connecting portion to the continuous perimeter, each radially elongated strip having a pair of longitudinal edges;
- such that when a moment is applied to a connection between the beam and the column, each radially elongated strip of the plurality of radially elongated strips experiences shear stress and undergoes plastic deformation, thereby damping relative movement between the beam and the column.
