Finite element analysis of buried steel pipelines under strike-slip fault displacements
(2011)The present paper investigates the mechanical behavior of buried steel pipelines, crossing active strike-slip tectonic faults. The fault plane is vertical and crosses the pipeline axis at a certain angle. The interacting ... -
Finite element analysis of damage in pipeline bends
(2010)The present paper describes a numerical formulation for the analysis of damage in steel pipeline bends. In particular, the numerical implementation of Gurson plasticity model is described in the framework of a special ... -
Mechanical behavior of buried steel pipelines crossing strike-slip seismic faults
(2011)The present paper investigates the mechanical behaviour of buried steel pipelines, crossing active strike-slip tectonic faults. The fault plane is vertical and perpendicular to the pipeline axis. The interacting soil-pipeline ... -
A new concept for improving the structural resilience of lap-welded steel pipeline joints
(2022)Lap-welded steel joints are widely used in steel pipelines for water transmission, and their structural resistance is essential for safeguarding pipeline integrity and functionality after severe earthquakes or other ... -
Numerical simulation of buried steel pipelines under strike-slip fault displacements
(2011)The paper examines the structural response of buried butt-welded steel pipelines, crossing active strike-slip tectonic faults, which are vertical and perpendicular to the pipeline axis. The interacting soil-pipeline system ... -
Safeguarding the integrity of large-diameter steel pipelines subjected to differential ground settlements
(2021)The paper describes the application of a novel and promising concept, aimed at absorbing ground-induced displacements due to soil subsidence in buried steel pipelines entering or exiting concrete or rigid structures. In ... -
Steel elbow response under strong cyclic loading
(2012)The present study examines the behavior of steel pipeline elbows subjected to strong cyclic loading conditions. A set of experiments is conducted where in-plane cyclic bending with constant amplitude is applied on the elbow ... -
Structural behavior of buried pipe bends and their effect on pipeline response in fault crossing areas
(2017)Pipe bends, often referred to as “elbows”, are special pipeline components, widely used in onshore buried steel pipelines. They are sensitive to imposed deformations and their structural behavior is quite flexible and ... -
Structural integrity of steel hydrocarbon pipelines with local wall distortions
(2014)Local distortions on pipeline wall in the form of dents or buckles may constitute a threat for the structural integrity of the steel pipeline. In the present paper, experimental research supported by numerical simulation ...
