PIPELINE BEAM MODELS USING STIFFNESS PROPERTY DEFORMATION RELATIONS

In this paper, a large displacement formulation of soil-beam pipeline interaction is reviewed and two methods of integration are demonstrated. The methods, one-dimensional integration of section-property-deformation relationships and three-dimensional volume integration, yield the same results for finite element analysis of pipe that does not buckle and for deformation paths of typical settlements. This occurs even though the section-property-deformation relationships are, theoretically, nonintegrable. Similar results are shown for a softening material. Based on the fact that the characteristics of section-property-deformation curves that include the effect of wrinkling can be modeled by the latter type curve, it argues that the analyses have established a reliable method of analysis for a pipe that deforms into the local buckling range. In addition, it illustrates that the effect of softening is to create a localized area in which the curvatures concentrate, that is, a wrinkle forms, while curvatures at other sites decrease. The section-property-deformation relationships used to solve the problems are extracted from three-dimensional shell analyses.
