Contraflexure 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. [1]

Nov 3, 2025 · The concept of contraflexure is a fundamental aspect of structural engineering that dictates the stability and design of buildings and bridges. While a structure’s ability to resist …

Dec 15, 2022 · A point of contraflexure in a structure is the point where the bending moment changes signs from positive to negative (and vice versa). In other words, it is a point where the …

A point of contraflexure is a point where the curvature of the beam changes sign. It is sometimes referred to as a point of inflexion and will be shown later to occur at the point, or points, on the …

Nov 7, 2025 · The point of contraflexure divides the beam into two parts — one in sagging and the other in hogging. This helps engineers decide where reinforcement is needed in beams made …

The meaning of CONTRAFLEXURE is a bending in opposite directions like the curve of an ogee; also : the point where this occurs : a point of contrary flexure or inflexion that in a fixed beam is …

Contraflexure refers to the point on a beam where the bending moment changes sign from positive to negative or vice versa, resulting in a zero bending moment (M = 0).

When a beam is subjected to a load, it bends, and the point of contraflexure is where the bending moment changes direction, marking a critical point in the beam's behavior.

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 …

Knowing the place of the contraflexure is especially useful when designing reinforced concrete or structural steel beams and also for designing bridges. Flexural reinforcement may be reduced …
