Hardy Cross - Hardy Cross Method

Hardy Cross Method

Hardy Cross's description of his method follows: "Moment Distribution. The method of moment distribution is this:

  1. Imagine all joints in the structure held so that they cannot rotate and compute the moments at the ends of the members for this condition;
  2. at each joint distribute the unbalanced fixed-end moment among the connecting members in proportion to the constant for each member defined as "stiffness";
  3. multiply the moment distributed to each member at a joint by the carry-over factor at the end of the member and set this product at the other end of the member;
  4. distribute these moments just "carried over";
  5. repeat the process until the moments to be carried over are small enough to be neglected; and
  6. add all moments – fixed-end moments, distributed moments, moments carried over – at each end of each member to obtain the true moment at the end."

Famous quotes containing the words hardy, cross and/or method:

    “And ghosts then keep their distance; and I know some liberty.”
    —Thomas Hardy (1840–1928)

    “Men are not to be told anything they might find too painful; the secret depths of human nature, the sordid physicalities, might overwhelm or damage them. For instance, men often faint at the sight of their own blood, to which they are not accustomed. For this reason you should never stand behind one in the line at the Red Cross donor clinic.”
    —Margaret Atwood (b. 1939)

    “Steady labor with the hands, which engrosses the attention also, is unquestionably the best method of removing palaver and sentimentality out of one’s style, both of speaking and writing.”
    —Henry David Thoreau (1817–1862)
