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 = 390 mm tw = 12 mm d = 100 mm t = 6.4 mm Additionally: • The area of each pipe is A = 1882 mm2. • The moment of inertia of the entire beam cross section about the z centroidal axis is IZ = 171660000 mm4. If the beam will be subjected to a shear force of V = 175 kN, determine the shear stress at point H, located at yH = 100 mm above the z centroidal axis.
