Question
A simply supported beam is reinforced with 4 – 28 mm ø at the bottom
and 2 – 28 mm ø at the top of the beam. Steel covering to centroid of
reinforcement is 70 mm at the top and bottom of the beam. The beam
has a total depth of 400 mm and a width
of 300 mm. fc’ = 30 MPa, fy = 415 MPa. Balanced steel ratio ρb = 0.031.
Compute the ultimate moment capacity of the beam in kN-m. Use
reduction factor of 0.90
