Rigid Connections

  • Elias G. Abu-Saba


The method of plastic analysis is based on the premise that connections are rigid. Thus, connections play a significant role in the design of indeterminate structures. The basic requirements for the condition of rigid connections are:
  1. 1.

    Sufficient strength of the connections to absorb (resist) the moments in the frame as a result of the given loads.

  2. 2.

    Adequate rotation capacity in the joints to provide sufficient redistribution of the moments.

  3. 3.

    Attainment of an overall stiffness for the structure to keep the displacements small.

  4. 4.

    Cost of fabrication must remain economical to provide an overall reduction in the cost of construction.
