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
tw = 16 mm
d = 120 mm
t = 4.8 mm
Additionally:
• The area of each pipe is A = 1737 mm2.
• The moment of inertia of the entire beam cross section about the z centroidal axis is IZ = 254790000 mm4.
If the beam will be subjected to a shear force of V = 250 kN, determine the shear stress at point K, located at yK = 80 mm below the z centroidal axis.
