ABSTRACT:
An energy dissipating device, particularly for use in structures impervious to seismic occurrences, includes a metal element having the shape of at least a symmetrical double portal, which is asymmetrically deformable in the elastic field or beyond the elastic limit. The center pier of this portal is fastened to one portion of the structure, whereas the two side piers are fastened to another portion of the structure so as to compel this metal element, upon a relative movement of the two portions of the structure, to be deformed in the elasto-plastic field, thereby dissipating the deformation work by hysteresis of the material principally in the form of heat.
