Answer / sjtbehera

Point of the Contraflexture is the point where Bending
moment value is 0. or other way where Bending moments
begins to change.

Flexural reinforcement may be reduced at this point.
However, to omit reinforcement at the point of
contraflexure entirely is inadvisable as the actual
location is unlikely to realistically be defined with
confidence. Additionally, an adequate quantity of
reinforcement should extend beyond the point of
contraflexure to develop bond strength and to facilitate
shear force transfer.

Answer / arumugam nagamani

'contra' means opposite. 'flexure' means bending. The
physical meaning is 'Contra flexure is a point where the
hogging of the beam changes to sagging or vice versa'. Also
the point where the bending moment changes its sign, i.e.
where bending becomes zero while changing from positive to
negative or negative to positive value.

Answer / arun

where the bending moment becomes 0.. or change of b.m i.e -
ive to +ive or vice verca.. and that point shear force
becomes high...

Answer / adhi devender

where the bending movements changes signs

Answer / zakir rahman

THE POINT AT WHICH THE BENDING MAOMENT IS ZERO THAT POINT
IS CALLED AS POINT OF CONTRAFLEXURE

Answer / rs

it is a point at which the bending moment curve intersects
with the zero line.

Answer / mohammed sona ullah

The point where the B.M. changes sign... or the Shear Force
is maximum.

Answer / mageswari

point of contraflexure is a point where the B.M is zero or
changes its sign.

Answer / shankar reddy

A point of contraflexure occur-es where the BM in a beam changes its sign. so, obviously at the point of contraflexure the bending momentum will be zero and as well as it changes sign.

Answer / sisir r prusty

it is the point where the bebding moment changes its direction i.e -ve bending moment to +ve bending moment & vice versa.
