Abstract
Pipelines, risers and piping systems are subject to internal and external pressures as well as
variations in temperature due to natural variations in the surrounding environment and
variations in content temperature. Pressures and, depending on the boundary conditions,
temperature will cause stresses in the pipe wall. Integrating the axial stresses over the cross
section of a pipe gives the so-called true wall axial force [1]. The global bending behavior of
pipes is affected by the axial force through 2nd order effects. However, due to the effect of the
internal and external pressures it is the so-called effective axial force that governs the global
response of the pipe. By using Archimedes’ law, Sparks [2] demonstrated that the
overall effects of pressure on a pipe may be expressed by an equivalent force system
where equivalent axial forces replace complicated pressure integrals over doubly curved
surfaces. Note that these equivalent axial forces do not cause axial stresses in a
pipe, hence the distinction between true wall axial force and effective axial force,
but they do, however,
govern static and dynamic beam bending behavior and buckling [1-3].
