Question
1. A reinforced concrete beam has a width of 300 mm and an effective depth of 618 mm. Compressive reinforcement (if required) will be placed at d’ = 60mm. f’c = 28 MPa and fy = 415 MPa. Use 2010/2015 NSCP. Use ? = 0.90 for flexure. At ultimate condition U = 1.2D +1.6L.
a) If the beam is to support a bending moment of 240 kN-m from dead load and 195 kN-m from live load, determine the required design flexural strength of the section.
b) If the beam is to support a bending moment of 240 kN-m from dead load and 195 kN-m from live load, determine the number of 28mm bars required as tension reinforcement
