The stress distribution in, and adjacent to, an externally-loaded frame in a cylin¬drical shell is extended to include the effects of discontinuities of circumferential-bending stiffness in the axial direction. These effects may be caused by nearby heavy frames, planes of symmetry and antisymmetry, and free ends. Such problems can be solved with the aid of the "transmission" matrix for a finite length of shell. A complete derivation for the elements of this matrix is given, which defines the force-displacement relationships at the ends of a finite length of shell. In addition to indicating exact solutions, this report derives an approximate technique and applies it to a number of practical problems.
