Buckling analysis of buried pipes subjected to fault movements

Buckling responses of buried pipes to fault movement considering the interaction of pipes and soil are analysed, using the Finite Displacement Analysis Method with thin shell elements. The analysis model of interaction of pipe and soil is presented. The pipe is discretized into 4 nodes thin thin shell elements and the soil is modeled by nonlinear springs. Some factors and parameter effects, such as material nonlinearity of the pipe and soil and the geometrical parameters of pipe are studied.
