SITUATION 2: A reinforced concrete cantilever beam has a span of 5m. It supports a factored load of 40kN/m applied 250mm off the centerline of the cross-section of the beam. It has a width of 400mm and an effective depth of 600mm with a total height of 650mm. It is reinforced in tension with 4-25mm diameter bars and 2-16mm diameter bars for compression. Design the beam for shear and torsional web reinforcements using 10mm diameter bars and design also the additional longitudinal reinforcement for torsion. Neglect the weight of the beam. Use NSCP 2010 and detailed analysis for nominal shear strength of concrete. Draw the section of the beam along with the shear and longitudinal reinforcements. Use 16mm diameter bars for middle longitudinal torsional reinforcements. f'c = 20.7MPa; fy = 275.8MPa
