Importance of contraflexure
WitrynaFor this purpose we use the task “Steel - Resistance of Cross Sections” in SSD. Select the elements to be designed. Framed in red below are the already mentioned “dummy” Structural Lines. ... Secondly we select … 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.
