Abstract

A damper device to protect structures such as road bridges and the like against earthquakes, which achieves the desired damping effect through direct displacements together with dimensions which are unusually compact, comprises two opposing plate-like bases in a predetermined position and at least two C-shaped members which deform elastically/plastically lying in corresponding planes perpendicular to the plane of the bases with the ends of the limbs of the C fixed to the said bases, the said planes forming an angle of 90 degree C between them. <IMAGE>
