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."

    “And so, standing before the aforesaid officiator, the two swore that at every other time of their lives till death took them, they would assuredly believe, feel, and desire precisely as they had believed, felt, and desired during the few preceding weeks. What was as remarkable as the undertaking itself was the fact that nobody seemed at all surprised at what they swore.”
