Sway Frame, Stuck with finding sway factor! (Moment Distrubution)

  1. Nov 8, 2009 #1
    1. The problem statement, all variables and given/known data
    I have a sway case beam as in the image below, but do not know the equation for the pinned joints.

    We were told Moment (AB) = 6EI(delta)/Lsquared
    for fixed ends such as AB and BA but not told the moment equation for CF for example.

    I am assuming FC = 0 due to no moment at the pin but I cannot go further with my distribution table before knowing these values.

    Edit: I have the proping force of 42.25kN already and everything before this, we were told to use an abitory moment but this was good in the example if all the lengths and EI's were the same.

    For anyone else needing to know this its 3ei(delta)/L squared :) and 0 for the pin.
