Significance of the point of contraflexure
Web, 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. WebJul 23, 2008 · I have been told numerous different things about what is the correct point of fixity to use. Some engineers have said that it is the point of zero deflection. Others say it is the second point of contraflexure of the displacement curve (if the pile is fixed at the top) and others say it is the second point of curvature of your moment curve.
