Point of contraflexure in fixed beam
In solid mechanics, a point along a beam under a lateral load is known as a point of contraflexure if the bending moment about the point equals zero. In a bending moment diagram, it is the point at which the bending moment curve intersects with the zero line (i.e. where the bending moment reverses direction along the beam). Knowing the place of the contraflexure is especially useful when designing reinforced concrete or structural steel beams and also for designing bridges.

Webrestraint system to the buckled shape of the critical compression flange of a beam, consider a brace with a central strut of stiffness k. The buckled shape of the strut is dependent on the brace stiffness. If the brace possesses adequate stiffness, a point of contraflexure will occur at this location (Figure 3 (c)), other- wise a bow
