Abstract
The performance of C1-continuous thin beam element is considered by using the error-moment equations derived from the energy functional. The analysis shows explicitly that the rigid body motions of a thin beam can be described correctly; and that the Barlow’s optimal stress points are re-interpreted as the optimal points in the limit sense, that is, true bending moment points and true shear force points converge to their optimal points respectively as the number of elements increases, on which examples are illustrated.
