Question

The beam cross section shown below has been proposed for a short pedestrian bridge. The cross section will consist of two pipes that are welded to a rectangular web plate. Dimensions of the cross section are:

h = 470 mm

t_w = 14 mm

d = 120 mm

t = 9.6 mm

Additionally:

• The area of each pipe is A = 3330 mm².

• The moment of inertia of the entire beam cross section about the z centroidal axis is I_Z = 428040000 mm⁴.

If the beam will be subjected to a shear force of V = 215 kN, determine the shear stress at point K, located at y_K = 80 mm below the z centroidal axis.
