Significance of the point of 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. 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. WebSep 6, 2024 · At the point of contraflexure, the bending moment is zero. For example: A propped cantilever beam with uniformly distributed load over the entire span. The …

WebMB = w. (a + b) (a-b)/2– w.a2/2. MB = w. (a2 - b2) /2– w.a2/2. MB = - w. b2/2. Bending moment at point B will be negative. As we can see here from above equation that bending moment at any section between A and B is following parabolic law and hence we can draw the bending moment diagram as displayed in above figure. WebNone of these. View Answer. A simply supported beam with a gradually varying load from zero at ‘B’ and ‘w’ per unit length at ‘A’ is shown in the below figure.
