AbstractA cyclic shear energy absorber for absorbing energy due to induced motion between two members by plastic cyclical deformation of a central energy absorber core. The core is surrounded by a restraining device having a rectangular cross section. Layers of the inner walls are separated by layers of resilient material. The restraining element is confined in a cylindrical aperture formed in a resilient support having alternately arranged resilient layers and stiffener layers. The absorber is confined between two end plates capable of being coupled to associated structural members, such as a bridge support column and a base.
