Transcribed Image Text:Practice Problem 7
The force P is acting along the centroidal axis of the welds at a distance "a" from weld (L2). Do not include
end turns.
Properties of vertical members:
2 angles 75 mm x 75 mm x 8 mm thick
Area of 2 angles = 2290 mm^2
F₁ = 248 MPa
F₁ = 400MPa
Allowable tensile stress based on gross area = 0.6Fy
Allowable tensile stress based on net area=0.5Fu
Properties of fillet weld:
Allowable weld shear stress = 0.3 Fu
Weld Ultimate stress, F = 414 MPa
Weld thickness= 8 mm
a) Which of the following gives the maximum tensile force P based on tension in the of the angles?
Use U= 0.85
b)
If L₁= 50 mm and L₂= 130 mm, which of the following gives the allowable load P based on shear in
the weld?
c)
If P= 540KN, which of the following gives the required length of weld at the right (L2), so that each
fillet is equally stressed in shear?
Gusset Plate
L₁
End Returns
