The nonlinear responses of two pipeline configurations, which are representative of an above-ground crude oil pipeline, are studied. Resistance to horizontal movement is provided by a combination of widely spaced anchor supports and intermediate friction supports. Following the application of operating pressure and thermal loads, the systems are subjected to strong earthquake ground motions. Results show that the inertia forces that develop during an earthquake tend to negate the restraining effect of the friction forces in the operating condition. This causes the pipe to move toward the position it would assume if there were no friction. The earthquake motion may result in either an increase or decrease in the critical bending moment depending on the geometrical configuration and the earthquake acceleration level.
