Steel structures miscellaneous

  1. ISA 100×100×10 mm (Cross sectional area = 1908 mm2) serves as tensile member. This angle is welded to a gusset plate along A and B appropriately as shown. Assuming the yield strength of the steel to be 260 N/mm2 the tensile strength of this member can be taken to be approximately.
    1. 500 kN
    2. 300 kN
    3. 225 kN
    4. None of &these
Correct Option: D

A1 =100 -
10
× 10 = 950 mm2
2

A2 = 950 mm2
Anet = A1 + K1 A2
= A1 +
3A1
A2
3A1 + A2

= 950 +
3 × 950
× 950
3 × 950 + 950

= 1662.5 mm2
