A 350mm x 500 mm rectangular beam is reinforced for tension only with 5 – 28mm dia bars. The beam has an effective depth of 446 mm. The beam carries a uniform dead load of 4.5 kN/m (including its own weight), a uniform live load of 3 kN/m and concentrated dead load of P and 2P as shown in the figure. Assume fy = 414 MPa and f'c = 34.5 MPa. Determine the following: a) The ultimate moment capacity of the section in kN-m. b) The maximum value of P in kN.

Transcribed Image Text:A 350mm x 500 mm rectangular beam is reinforced for
tension only with 5 – 28mm dia bars. The beam has an
effective depth of 446 mm. The beam carries a uniform
dead load of 4.5 kN/m (including its own weight), a
uniform live load of 3 kN/m and concentrated dead load
of P and 2P as shown in the figure. Assume fy = 414 MPa
and f'c = 34.5 MPa. Determine the following:
a) The ultimate moment capacity of the section in
