Analytical model for the strain analysis of continuous buried pipelines in geohazard areas
(2017)In geohazard areas, buried pipelines are subjected to permanent ground-induced deformations, which constitute major threats for their structural safety. Geohazards include seismic fault movement, liquefaction-induced lateral ... -
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 ... -
Buckling and classification of high-strength steel CHS tubular members under axial compression and bending
(2012)EN 1993-1-1 provisions classify high-strength steel CHS members with relatively low values of D/t ratio as Class 3 or 4, so that their strength is based on elastic behavior only, neglecting their capability of sustaining ... -
Buckling of clad pipes under bending and external pressure
(2011)The present paper concerns the structural behaviour of clad pipes. This is a double wall pipe, composed by two pipes that are in contact through an appropriate manufacturing procedure; a thick-walled carbon steel "outer ... -
Failure analysis of a welded steel pipe at Kullar fault crossing
(2017)The seismic response of a 2200-mm-diameter welded steel pipe at strike slip Kullar fault crossing in Izmit, Kocaeli during 1999 Kocaeli earthquake is investigated. The pipe was crossing the fault-line with an angle of 55° ... -
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 ... -
Local buckling and deformation capacity of tubes in steel structures
(2008)In this paper, the focus is on local buckling limits after yielding of the cross section (plastic buckling). This is in contrast to thin cylindrical shells, where local buckling occurs at stresses below the yield stress ... -
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 ... -
Local buckling strength and deformation capacity of pipes
(2009)Local buckling in cylindrical shells may occur elastically or plastically, mainly depending on the diameter to wall thickness ratio. In offshore structures plastic local buckling is mostly the governing criterion. In thin ... -
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 ... -
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, ... -
Structural resistance of high-strength steel CHS members
(2017)The structural resistance of high-strength steel seamless tubular beam-columns of circular cross-section subjected to axial compression and bending loading is investigated, using experimental testing and numerical finite ...
