A 16 mm thick gusset plate is connected to the 12 mm thick flange plate of an I-section using fillet welds on both sides as shown in the figure

Q. A 16 mm thick gusset plate is connected to the 12 mm thick flange plate of an I-section using fillet welds on both sides as shown in the figure (not drawn to scale). The gusset plate is subjected to a point load of 350 kN acting at a distance of 100 mm from the flange plate. Size of fillet weld is 10 mm.

The maximum resultant stress (in MPa, round off to 1 decimal place) on the fillet weld along the vertical plane would be_______________

Solution:

Given data :
Thickness of gusset plate (t) = 16 mm
Point load (P) = 350 KN
Eccentricity (e) = 100 mm

Throat thickness,
=0.7S=0.7×10=7 mm

Direct shear stress,
