Webb8 dec. 2011 · Consequently, it is not always sufficient to investigate the points of zero shearing force when determining the maximum bending moment. At a point on the beam where the type of bending is changing from sagging to hogging, the bending moment must be zero, and this is called a point of inflection or contraflexure. Webbbetween the point of contraflexure and the support, published guidance prohibits this. In the Designers’ Guide to EN 1994-1-11, section 6.4.1, we read “It should not be assumed that a point of contraflexure is equivalent to a lateral restraint”. In some situations, it is common practice to avoid the uncertainty altogether

WebbPoint of contraflexure: The point where a beam suffers no bending moment is also known as Point of contraflexure. Point of Inflexion: Inflection point is a point where a function turns from concave to convex, i.e it is point shown on the curvature diagram of the structure where the curvature changes from concave to convex. Webb27 sep. 2024 · The point of contra flexure is the location in a flexing (or bending) beam where there is no bending moment. The bending moment is either at its maximum or minimum when the shear force at a location is zero. Shear force is defined as dM/dx, where M is the load-induced bending moment. M is the maximum if Shear is zero. Webb10 apr. 2024 · “@unraveaero copies "sanghi" themes from other rss handles. I have covered the first two already. I will presently look at this one.
