WebbThe point of contraflexure in a loaded beam refers to the section where: Where bending moment diagram changes the sign known as point of contraflexure. WebbThe beams also bend in a two-fold curvature to resist the bending, with points of contraflexure roughly in the middle of the span. The overall shear racking of the frame is caused by the accumulated bending of the columns and beams. According to Fig. 3.4b, the deflected shape caused by this component has a shear deflection structure.
