Conversation so far:
where is the point of contra flexure
In a bending moment diagram, the point of contraflexure is the point at which the bending moment curve intersects with the zero line.
why is the point of contraflexure useful
Knowing the place of the contraflexure is especially useful when designing reinforced concrete or structural steel beams and also for designing bridges.
can reinforcement be omitted at the point of contraflexure
Omitting reinforcement at the point of contraflexure is considered inadvisable as, in a real-life situation, it may be difficult to locate the exact point of contraflexure.
can reinforcement be reduced at the point of contraflexure
Flexural reinforcement may be reduced at the point of contraflexure.
