Abstract
In antiseismic steel structural works of the frame type or of the truss type, which are constituted by columns and by girders fastened to the columns, the girders of different shapes show, at least in the vicinity of one of their extremities, a dissipative zone constituted by a reduction of the actual cross section. The reduction of the actual cross section consists either in differently shaped indentations in the edges of the flanges of the girder or in round or polygonal holes which are regularly distributed over the flanges and have a small diameter.
