Abstract

Determining the failure criteria and the level of damage in buriedpipelines is an important and significant issue and differentresearchers have studied continuous and segmented steeland concrete pipes. To calculate the failure criterion of GlassReinforced Polymer (GRP) pipes, first the pipe was tested andthe force-displacement diagram of the pipe was drawn up untilthe failure time. Then, the tested specimen was modelled usingfinite element software and the lab test results were verifiedquite accurately. Based on this, by the finite element modelingof GRP pipe with different diameters under bending, the pipe’sfailure criterion was calculated. Afterwards, straight GRPpipes with different diameters were subjected to landslide andearthquake wave propagation in different clay and sandy soils.The results of finite element analyses in eight different types ofsoil show the vulnerability of the GRP pipes.
