Bending deformation capacity of large-diameter spiral-welded tubes
(2014)Numerical simulations are conducted to define the bending deformation capacity of large-diameter spiral-welded tubes, towards efficient strain-based design. Under bending loading, the principal failure mode of those tubes ... -
Buried steel pipelines crossing strike-slip faults
(2012)The paper examines the behaviour of buried steel pipelines crossing active strike-slip faults. The vertical fault plane is crossed by the pipeline at an angle ranging between zero and 45 degrees, causing significant plastic ... -
The effect of spiral cold-bending manufacturing process on pipeline mechanical behavior
(2016)Large-diameter spiral-welded pipes are employed in demanding hydrocarbon pipeline applications, which require an efficient strain-based design framework. In the course of a large European project, numerical simulations on ... -
Local buckling limits of tubular sections in bending and compression
(2010)In design standards and recommended practices a large scatter can be observed in local buckling limits. Some can be explained from different design focuses and safety requirements but much is not clear. The traditional ... -
Strain-based design of a large-diameter steel water pipeline crossing ground settlement areas
(2021)This paper describes the structural design of a large-diameter buried steel pipeline crossing two areas of substantial soil settlement, which impose fault-type actions in the pipeline. Those ground-induced deformations are ... -
Strain-Based design procedures for spiral-welded steel tubes in combined walls
(2016)Spiral-welded steel tubes with diameter to wall thickness ratios between 60 and 140 are often employed in combined wall systems with local buckling as governing failure mode. The current design rules in Eurocode 3 (EN ... -
Strain-based design rules for Spiral-welded tubes using analytical modelling
(2016)Spiral-welded steel tubes with diameter to wall thickness ratios between 60 and 140 are often employed in combined wall systems with local buckling as governing failure mode. In a European research project called Combitube, ... -
Ultra low-cycle fatigue performance of S420 and S700 steel welded tubular X-joints
(2019)The present study is motivated by the need for improving the fatigue performance of offshore wind energy structural systems. In particular, the ultra low-cycle fatigue performance of welded tubular X-joints is examined, ... -
Wrinkling of lined pipes under bending
(2012)The present study is motivated by the use of lined pipes in energy pipeline applications (oil, gas, etc.) where a corrosion-resistant thin-walled liner is fitted inside a carbon-steel outer pipe. The paper focuses on ...
