A 350 mm x 500 mm rectangular beam carries a uniform dead load of 4.5 kN/m (including its own weight) and uniform live load of 3 kN/m. If a concentrated live load P 150 kN was added as shown in the figure, a) calculate the tension steel area required to support the loading. b) determine how many 20 mm diameter rebar was needed. c) draw the cross-section of the reinforced rectangular beam.
