We propose a procedure for the evaluation the parameters of brittle and ductile fractures of multisupport overhead sections of pipelines weakened by annular semielliptic cracks, which takes into account the membrane, global couple, and residual welding stresses. To describe the process of bending of pipeline, we use the model of a beam with piecewise variable stiffness with regard for the elasticity and possible displacements of the supports, and soil masses.
