A rectangular fixed supported beam
has the following properties.
Compression steel if required shall
have its centroid "d " mm from the
extreme fiber. Calculate the required
steel area (mm) at the midspan and
end supports of the beam. Sketch the
location of the reinforcements. Use
23.6 kN/m for the unit weight of
the concrete. Round off your final
answer in 3 decimal places.
Given:
width of beam, b = 450 mm
depth of beam, h = 650 mm
clear cover up to
center of tension 60

Length of beam = 12
MIDSPAN:
Required Tension Steel Area =
