Dynamic and Probabilistic Analysis of Shear Deformable Pipeline Resting on Two Parameter Foundation

Abstract

The nonlinear dynamic deterministic and probabilistic analysis of pipeline undergoing large deflections and resting on Winkler-Pasternak foundation have been done. Dynamic analogues of Euler Bernoulli and Timoshenko Von-Kármán type beam equations are used. The stochastic finite element approach based on the Vanmarcke method combined to Monte Carlo simulations has been used to solve the governing nonlinear equations of soil-pipe interaction. The influence of different parameters of random soil is has been analyzed and the obtained results are compared with those obtained from the literature. It is concluded from the present work that the spatial variability of the soil properties has a great impact on the seismic response of the pipe and the developed model which is based on the accurate method is efficient to determine the real response of the safe and economic pipeline.

The effects of nonlinear soil spatial variability on the nonlinear beam response

“…Griffiths, Paiboon, Huang, and Fenton (2008) employed a probabilistic approach to analyze the behavior of laterally loaded piles supported by random Winkler soil. The linear dynamic response of pipes resting on random soil has also been studied (Nedjar, Hamane, Bensafi, Elachachi, & Breysse, 2007;Seguini & Nedjar, 2020). Additionally, various models have been developed to assess the probabilistic behavior of pipes.…”

Machine Learning for Predicting Pipeline Displacements Based on Soil Rigidity

“…To investigate the nonlinearity effect of the soil's on the behaviour of the beam, Seguini and Nedjar [14] performed a series of tests and simulations by using the nonlinear analysis [15][16]. In addition, recent research has been done on soil-structure interaction including the dynamic stochastic analysis of the pipeline [17][18][19]. In fact, Seguini and Nedjar [19] provided an accurate numerical modelling of the pipeline involving the seismic effect.…”
