An analytical and experimental investigation on the effects of placing flexible joints in the vicinity of buried pipeline junctions evaluated the following important variables: (1) flexibility of rubber-gasketed pipeline joints, (2) bending and axial stiffness of cast-iron pipe barrels and joints, (3) modulus of soil foundation and direct soil shear effects, and (4) variations in the network topology of intersecting pipelines. Design can lessen junction stresses caused by seismic forces by placing flexible pipe joints near the junctions and selecting an appropriate spacing between intersecting pipes.
