Structure having stress protected groove weld and structural members forming the same

A 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) includes a root protrusion (22) extending radially outward from the second surface (18) along a root pr...

Beschreibung
Zusammenfassung:	A 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) includes a root protrusion (22) extending radially outward from the second surface (18) along a root protrusion radius to an outer end of the root protrusion (22) to define a root protrusion height extending from the second surface (18) to the outer end. The root protrusion (22) further includes a root protrusion width extending between an inner edge and an outer edge of the outer end. 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 flow path propagated through the body (40) of the structural member (10).
