Buried steel pipelines crossing strike-slip faults
Vazouras, P.; Karamanos, S. A.; Dakoulas, P. (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
Vazouras, P.; Karamanos, S. A.; Dakoulas, P. (2010)The present paper investigates the mechanical behavior of buried steel pipelines, crossing an active strike-slip tectonic fault The fault is normal to the pipeline direction and moves in the horizontal direction, causing ... -
Finite element analysis of buried steel pipelines under strike-slip fault displacements
Vazouras, P.; A.karamanos, S.; Dakoulas, P. (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 ... -
Health monitoring of Metsovo bridge using ambient vibrations
Panetsos, P.; Ntotsios, E.; Papadimitriou, C.; Papadioti, D. C.; Dakoulas, P. (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 ... -
Insight into seismic earth and water pressures against caisson quay walls
Dakoulas, P.; Gazetas, G. (2008)Motivated by the need to explain the large displacement and rotation that numerous caisson-type quay walls suffered in the port of Kobe during the devastating 1995 earthquake, a detailed numerical analysis is presented for ... -
Liquefaction performance of shallow foundations in presence of a soil crust
Bouckovalas, G.; Dakoulas, P. (2007)Liquefiable soils are currently categorized by all seismic codes as extreme ground conditions where, following a positive identification of this hazard, the construction of surface foundations is essentially allowed only ... -
Longitudinal vibrations of tall concrete faced rockfill dams in narrow canyons
Dakoulas, P. (2012)Longitudinal vibrations of concrete-faced rockfill dams may cause significant compressive stresses and joint openings in the slab panels. The behavior of such dams subjected to longitudinal and vertical vibrations is ... -
Mechanical behavior of buried steel pipelines crossing strike-slip seismic faults
Vazouras, P.; Karamanos, S. A.; Dakoulas, P. (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 ... -
Mechanical behavior of buried steel pipes crossing active strike-slip faults
Vazouras, P.; Karamanos, S. A.; Dakoulas, P. (2012)The present paper addresses the mechanical behavior of buried steel pipes crossing active strike-slip tectonic faults. The pipeline is assumed to cross the vertical fault plane at angles ranging between zero and 45 degrees. ... -
Non-linear 3D simulation of the construction and impounding of a CFRD
Dakoulas, P.; Thanopoulos, Y.; Anastassopoulos, K. (2008)A general methodology for the non-linear 3D numerical simulation of the phased construction and subsequent reservoir impoundment of a concrete faced rockfill dam built in a narrow canyon is presented. The common characteristic ... -
