Numerical Analysis of Buried Pipelines with Right Angle Elbow under Wave Propagation

An efficient numerical approach for simulating soil-pipe interaction behaviour under cyclic loading

“…While this methodology is simple, computationally efficient, and features frequently in the literature (e.g. Takada and Tanabe 1987, Lee et al 2009, Saberi et al 2011a, 2011b, it cannot capture certain pipe damage modes such as local buckling and ovalization. For this reason, the pipe has also been modelled using shell elements in the literature, as shown in Figure 1-b (e.g.…”

Influence of the topographic effect on the seismic response of buried pipelines

“…Because it is difficult for a beam model to analyze large deformation in pipe cross-sections as well as the interaction with the surrounding soil, a shell element was used to model the pipeline system in both the 2D and 3D models. The FE shell model has been previously proposed for this purpose (Behnamfar et al 2013;Datta, 1999;Duhee et al 2020;Kouretzis et al 2006;Saberi et al 2011Saberi et al , 2015Takada and Higashi 1992;Oskouei and Ghaznavi, 2017;Rahimi et al 2019). Mitani et al (2012) emphasized the ability of ABAQUS to investigate topographic effects on the amplification of seismic motion.…”

Study of the seismodynamics of spatially located underground pipelines with a nodal connection of non-orthogonal configuration

“…E.N. Figarov and many others who dealt with seismic resistance of structures working in the world's leading scientific centers, universities, and research institutes [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20].…”
