A shell model analysis can calculate the cross-sectional deformation and hoop stress of buried pipelines. This paper proposes an analytical method to calculate the response of buried straight and bent pipelines modeled as cylindrical shell structures. A modified transfer matrix method is employed instead of a stiffness matrix method to avoid the problem of computational memory caused by huge matrixes. Results calculated by the developed program are compared with experimental ones obtained by a pipe bending test of straight and bent pipe segments. In addition, several differences of the pipe response between the beam model and the shell model are examined through response simulations of straight and bent pipelines subjected to ground subsidence.
