Design includes service life,risk,mitigation,etc.The basics of pipe design are strength and pipe stiffness.Soil - The structural mechanics of buried pipes is not simply the mechanics of a pipe under pressure - internal or external.In many cases,soil contributes more to structural performance of a conduit than does the pipe.Structural design of buried pipelines for severe Apr 01,2001 guidelines for the design of buried steel pipe#0183;When a seismic wave excites the ground,the buried piping structures such as bends experience additional stresses.If such structures are subjected to a seismic wave of apparent wave length L a propagating in the direction of branch pipe shown in Fig.4 where the solid line is the ground motion with the maximum amplitude U h and the shadow edge is pipe displacement,the largest
