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 ... -
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 sloshing in AXI-symmetric vessels
(2008)The present paper investigates externally-induced sloshing in axi-symmetric liquid containers, with emphasis on industrial spherical containers, using an efficient numerical formulation, based on modal analysis. Assuming ... -
Health monitoring of Metsovo bridge using ambient vibrations
(2010)A real-time online structural health monitoring system for the Metsovo bridge, the highest R/C bridge of the Egnatia Odos Motorway in Greece, is outlined and then used to develop high fidelity dynamic finite element models ... -
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 ... -
Numerical implementation of J 2 non-associative flow plasticity models
(2009)The present paper describes a J2 non-associative plasticity model, which takes into account the "corner-like" effects at the loading point on the yield surface, and is suitable for shell buckling calculations. The plastic ... -
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 ... -
On the seismic behaviour and design of liquid storage tanks
(2011)The paper examines some special issues on the structural behaviour of upright-cylindrical liquid storage tanks, which are widely used in industrial facilities and for water storage. Two main design standards are considered: ... -
Strength and stability of High-Strength Steel tubular beam-columns
(2012)In this study, the structural behavior of high-strength steel tubular CHS seamless structural members under combined loading of axial compression and bending is examined. The work is mainly numerical supported by a series ... -
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 ...
