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. Witryna31 gru 2016 · Point of contraflexure In B.M diagram, The point at which B.M change its sign from positive to negative or negative to positive is called point of contraflexure. It is a point where the beam tends to bend in opposite direction. It is the point at which curvature of beam changes. 31/12/16 RAVI VISHWAKARMA 11 12.
