A reinforced concrete beam of normal weight concrete with an effective depth of 20 IN and a width of 12 IN is reinforced with 3 IN2 of grade 60 (fy = 60 KSI) rebar. The beam has a concrete compressive strength f’c of 3000 PSI.
(a) Determine the maximum ultimate moment which can be applied to the beam.
(b) If the only dead load on the beam is self-weight, determine the allowable uniformly distributed live load which can be applied to the beam. Assume an 18 FT span (simply supported) and 2.5 IN of cover over the reinforcement.

1.A reinforced concrete beam having a width of 500 mm and an
effective depth of 750 mm is reinforced with 5 – 25mm φ. The beam
has simple span of 10 m. It carries an ultimate uniform load of 50
KN/m. Use f’c = 28 MPa, and fy = 413 MPa. Determine the value of fs
in MPa. Express your answer in two decimal places.

A reinforced concrete beam has square cross section (h × h).
There are 9 steel reinforcing bars (each of diameter ds), 3 evenly
spaced towards the top, 3 along the neutral axis, and 3 evenly
spaced towards the bottom. The vertical distance from the centre of
the bar to top (or bottom) edge of the section is called the cover,
and is denoted as e. It should be taken that ρsteel = 7850 kg/m3,
ρconcrete = 2350 kg/m3, Econcrete =...
