Cylindrical shells having pipe attachments and branches are extensively used in many industrial installations. Boilers, reactors, and cylindrical tanks are obvious examples. In this investigation the solution to the problem of stresses and displacements at the intersection of a simply supported circular cylindrical shell with a pipe attachment subject to a uniform load on its top is derived. It is assumed that the axes of the two cylindrical shells are intersecting and that they are perpendicular. Numerical values of stress resultants and stress couples at various points along the intersection curve of the two shells for several geometrical configurations are presented.
