Stiffened shear panels.

[quyn123]

Hey guys.

The question states:for the following beam, find the axial loads in the stiffening rods and the shear loads acting on each of the following edges.

I basically worked out the shear for the panels by making an imaginary cut and letting internal momment equal to zero. Giving 70.7KN on the two most horizontal and 30KN on the vertical . The part that I am stuck is is how do I calculate the the axial loads in the stiffening rods?

Cheers for the help.

quyn123: I would say the axial force (in kN) in the vertical stiffening rod is 30 - 0.5*y, where y is in units of mm. The axial force (in kN) in the upper, almost horizontal stiffening rod is 0.505 076*x. The axial force in the lower, almost horizontal stiffening rod is -0.505 076*x. I would say the shear flow on all four edges of the panel web is q = 0.50 kN/mm.

Hi there,

Calculating the axial loads in the stiffening rods involves analyzing the forces acting on the beam and using the principles of statics. Here are the steps you can follow:

1. Draw a free body diagram of the beam, including all the forces acting on it (axial loads, shear loads, and any external loads).
2. Apply the equations of equilibrium to the beam to determine the reactions at the supports.
3. Use the method of sections to cut the beam at the location of the stiffening rods. This will create a section of the beam with the stiffening rods acting as internal forces.
4. Apply the equations of equilibrium to this section, considering the internal forces from the stiffening rods.
5. Solve for the axial loads in the stiffening rods using the equations of equilibrium.

Hope this helps! Let me know if you have any further questions.
