About this detail

A structural steel truss chord splice incorporates an aligned flange thickness transition. A cover plate matches the thickness, grade, and width of the smaller flange truss chord, located typically on each side of the splice. Complete joint penetration welds connect the members at the centerline splice, while a two-and-a-half to one slope transition accommodates the change in flange width and thickness. This condition applies similarly to both top and bottom chords when their centerlines align.
