1) A designer has selected a W250 BY 22 section for the 3m cantilever beam shown below. The beam is supporting a porch in a residential building. The factored loads on the beam include a uniformly distributed load of 5 KN/m acting over the entire length and a point load of 20 KN at a distance of 1m from the free end. The member is laterally supported only at its ends (A and C). Use ASTM A992 steel. (Fy = 345 Mpa), E = 200000 Mpa and G = 77000 Mpa By manual calculations, check the adequacy of the beam for carrying the factored moment. The bending moment distribution is not considered effectively linear. All manual calculations are required. No need to check for shear resistance, bearing resistance, and deflection.
