Abstract

Earthquakes can cause a lot of damages to buried pipelines. When pipelines are placed in a seismically active area, in addition to safety, performance, and environmental criteria, ground displacement hazards such as fault movements should be considered carefully. Therefore, the present study was aimed to evaluate the response of buried pipelines crossing ground deformation especially faulting based on nonlinear approaches. Considering the pipe as SHELL Element, soil as SOLID Element, and also non-linearity of material and geometry, several caseloads of buried pipelines crossing fault were modeled in the ABAQUS software. Then, all the models were analyzed in both tensile and compressive modes by Push-over analysis method. As a result, besides extracting the relationship between flexural moment and bending angle, the average of obtained curves were normalized and the standard five-line behavior curves were fitted to them. The developed curves can be simply used in any simplified modeling applications for assigning the plastic hinges to different types of pipelines.
