Zusammenfassung:	A structural member (10) is disclosed. The structural member (10) includes a body (40) having a first surface (16), a second surface (18), and an end surface (42) at an end portion (20) of the structural member (10). The end portion (20) of the structural member (10) includes a root protrusion (22) extending radially outward from the second surface (18) of the structural member (10) along a root protrusion radius to an outer end (82) of the root protrusion (22) to define a root protrusion height extending from the second surface (18) of the structural member (10) to the outer end (82) of the root protrusion (22). The root protrusion (22) further includes a root protrusion width extending between an inner edge (184) and an outer edge (80) of the outer end (82) of the root protrusion (22). The root protrusion radius, the root protrusion height, and the root protrusion width are configured to define a stress protected weld root region (160) isolated beyond and away from a root stress flowpath (200) propagated th
