A floating, nondestructably disconnectable, discontinuous, full-moment nodal connection between the end of a beam and the side of a column including (a) a column having a side, (b) a column-mount node structure joined to that column side, (c) an elongate beam having an end, and (d) a beam-mount node structure joined to that beam end. The column-mount and beam-mount structures are floatingly, nondestructably disconnectably, and discontinuity-gravity-seated relative to one another, and as so seated, form an operative full-moment connection, via the node structures, between the column and beam, this connection being characterized by the fact that there is no uninterrupted material-occupying path or structure which flows structurally from the beam to the column through the node structures.
