Question { 28290 }

why reinforcement is not provided at centre for beams r column

Answer

The concrete weak in tension and strong in compression.
to resist the load in tension side reinforcement
provided.To make proper anchorage nominal reinforcement
provided in compression reinforcement.

if we provide reinforcement in center it canot contribute
either compression and tension.So no need to provide
reinforcement in center of beams.
If depth of beam large i.e more than 700mm normally we
provide extra reinforcement at center to hold the
compression reinforcement properly
But only in case when beam subjected torsion ,to resist
torsional moment we provide extra reinforcement in center.
