This paper is based on the pipe/soil interaction model, of uniform longitudinal friction forces where slippage occurs, and distributed linear springs resisting pipe lateral deflection. The long L-bend, the Z-bend with a short middle leg, and equal short lengths repeated in a Stair Pattern are analyzed, with the elbows idealized as torsion springs at junction points. For the long L-bend, a refined model including soil resistance to elbow deflection is also analyzed for comparison. The possibility of a semianalytical computer program for inter-connected unequal short lengths is considered.
