Special Note on Slope-Deflection and Fixed End Moments It is important to realize that the Slope-Deflection equations implicitly contain the relative linear displacement term, . The fixed end moment for the near end (N = near end F = far end) of a beam segment subjected to a relative displacement, is given in the back of the book as, FEM EI L N =− 6 2 (1) The Slope-Deflection equation for the near end of a beam segment given as, M LL FEM NN F N = +− + 22 3 θθ Rewriting, M L L FEM F N = + [] + 6 2 Note that the relative displacement term, ∆, within the Slope-Deflection
