The paper illustrates in accordance with the criteria of EN 1993-1-8 and NTC 2008 the verification of the components of a "structural node" consisting of a column welded to a base plate connected to the foundation with anchor bolts ("moment resisting column base") and subjected to seismic stresses.

With the provision of "dissipative zone" at the base of the column, the concept of overstrength of the node with respect to the column is applied, and the control of "strength hierarchy" of nodal components is carried out for structures with medium or high ductility class.

The anchorage of columns with interlocking at the footing
