✦ Synopsis

A symmetry extension of Maxwell's rule for rigidity of frames is found. This rule subsumes and strengthens Maxwell's 1864 rule by requiring that the internal and external degrees of freedom of a pin-jointed structure are not only numerically equal, but are also equisymmetric. A number of special cases of Maxwell's original rule are studied to show the improved insight that the symmetry-adapted version can give.

At the initial design stage, for rapid evaluation of strength of ship structures, finite element analysis using beam elements is carried out as a rule. In beam modeling of ship structures, brackets are usually represented by rigid elements to simpliJ~ the analysis. The extent o frigid ends, which is
