AISC 13th said:For welded cover plates, the welds connecting the cover plate termination to the
beam or girder shall have continuous welds along both edges of the cover plate
in the length a', defined below, and shall be adequate to develop the cover plate’s
portion of the strength of the beam or girder at the distance a from the end of
the cover plate.
(a) When there is a continuous weld equal to or larger than three-fourths of the
plate thickness across the end of the plate
a' = w (F13-5)
where
w = width of cover plate, in. (mm)
(b) When there is a continuous weld smaller than three-fourths of the plate thickness across the end of the plate
a' = 1.5w (F13-6)
(c) When there is no weld across the end of the plate
a' = 2w (F13-7)
