The flange and web plates of the doubly symmetric built-up section are connected by continuous 10 mm thick fillet welds as shown in the figure (not drawn to the scale). The moment of inertia of the section about its principal axis X-X is 7.73 × 106 mm4. The permissible shear stress in the fillet welds is 100 N/mm2. The design shear strength of the section is governed by the capacity of the fillet welds.

The maximum shear force (in kN, round off to one decimal place) that can be carriedby the section, is _______.
    Correct answer is '393.5'. Can you explain this answer?
    Verified Answer
    The flange and web plates of the doubly symmetric built-up section are...

    q = Shear stress at the level mn in the weld = 100 MPa 
    F =  Shear force at the given section
    A = Area of the cross-section above the level mn = 100 × 10 mm2
     C.G. of shaded area above the level mn = 60 – 5 = 55 m
    I = 7.73 × 106 mm4
    b = Width of weld at mn (4 welds) = 4 × t = 4 × 7 = 28 mm
    t = Throat thickness
    = 0.7 × s = 0.7 × 10 × 4 = 28 mm
    ∴ 

    = 393.5 kN
