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. Webb, should be taken from the face of the column to the point of contraflexure, when the beam is composite with the floor slab away from the column face, and the section restraint is taken as F at the column face and P at the point of contraflexure. The bending moment gradient over the segment can be taken as triangular, giving m = 1.75.
