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.(a) 1795 mm2(b) 1812 mm2(c) 1956 mm2(d) 2100 mm2I had been asked this question in quiz.Question is taken from Design of Tension Members in section Design of Tension Members of Design of Steel Structures

Answer»

The correct CHOICE is (c) 1956 mm2

For EXPLANATION I would SAY: Net area of CONNECTED leg, Anc = (100 – 12/2) x 12 = 1128 mm^2

Net area of OUTSTANDING leg, Ago = (75 – 12/2) x 12 = 828 mm^2

Total net area = 1128 + 828 = 1956 mm^2.
