Stresses in Beam Transitions of Main Gas Pipelines under Dynamic Loads

Abstract

The main dependences that make it possible to determine and evaluate the dynamic components of stresses and displacements in main gas pipelines under the action of a moving concentrated force are considered. The solution of the problem is given for single-span, two-span, and three-span beam transitions. According to the requirements of industry documents, decisions were made on the further operation of crossings or the need for their reconstruction.
