Determine the effective net area for angle section ISA 100 x 75 x 12 mm, when 100mm leg is connected to a gusset plate using weld of length 140mm.

Determine the effective net area for angle section ISA 100 x 75 x 12 mm, when 100mm leg is connected to a gusset plate using weld of length 140mm. Correct Answer 1956 mm2

Net area of connected leg, Anc = (100 – 12/2) x 12 = 1128 mm2 Net area of outstanding leg, Ago = (75 – 12/2) x 12 = 828 mm2 Total net area = 1128 + 828 = 1956 mm2.
