Calculate the tensile strength due to gross section yielding of an angle section 125 x 75 x 10mm of Fe410 grade of steel connected with a gusset plate.(a) 780 kN(b) 586.95 kN(c) 432.27 kN(d) 225.36 kNThe question was asked in final exam.Question is taken from Design of Tension Members in portion Design of Tension Members of Design of Steel Structures

Answer»

Correct answer is (C) 432.27 KN

The explanation is: FU = 410MPa, fy = 250MPa, γm0 = 1.1, γm1 = 1.25,

For ISA 125 x 75 x 10mm : gross AREA Ag = 1902 mm^2

Tensile strength due to gross section yielding, Tdg = Agfy/γm0 = 1902 x 250 x 10-3 / 1.1 = 432.27 kN.
