Answer Posted / beamers
Beams are not provided with reinforcement at the middle
(center)simply because stress at that section is minimal if
you know the strain diagram of a beam section, that even
you provide steel on center the beam will not utilized
these bar because these bar will not yield meaning
useless,but in practice if your beam depth is greater than
600 mm we provide side bars.One analogy is that if you are
using hollow tube either circular or rectangular,as beam or
column members even though its hollow still they can carry
much load because external fiber of section is most
stressed.
