Analysis of fault rupture propagation through uniform soil cover
Loukidis, D.; Bouckovalas, G. D.; Papadimitriou, A. G. (2009)This paper presents results from numerical simulations of the propagation of an active dip-slip fault rupture through a uniform soil layer covering the rigid bedrock. Following verification of the numerical methodology ... -
Bounding surface plasticity model for the seismic liquefaction analysis of geostructures
Andrianopoulos, K. I.; Papadimitriou, A. G.; Bouckovalas, G. D. (2010)This paper presents the constitutive relations and the simulative potential of a new plasticity model developed mainly for the seismic liquefaction analysis of geostructures. The model incorporates the framework of critical ... -
Explicit integration of bounding surface model for the analysis of earthquake soil liquefaction
Andrianopoulos, K. I.; Papadimitriou, A. G.; Bouckovalas, G. D. (2010)This paper presents a new plasticity model developed for the simulation of monotonic and cyclic loading of non-cohesive soils and its implementation to the commercial finite-difference code FLAC, using its User-Defined-Model ... -

Insight into the seismic response of earth dams with an emphasis on seismic coefficient estimation
Andrianopoulos, K. I.; Papadimitriou, A. G.; Bouckovalas, G. D.; Karamitros, D. K. (2014)This paper presents a numerical investigation of the seismic response of earth dams by employing results from 110 nonlinear two-dimensional (2D) dynamic analyses of four different cross-sections with heights ranging from ... -
Methodology for automated GIS-aided seismic microzonation studies
Papadimitriou, A. G.; Antoniou, A. A.; Bouckovalas, G. D.; Marinos, P. G. (2008)This paper presents an automated methodology for performing geographic information system (GIS)-aided seismic microzonation studies. It presupposes the existence of a geotechnical database containing data from sampling ... -
Methodology for estimating seismic coefficients for performance-based design of earthdams and tall embankments
Papadimitriou, A. G.; Bouckovalas, G. D.; Andrianopoulos, K. I. (2014)Following an overview of pertinent literature, this paper presents a new methodology for estimating seismic coefficients for the performance-based design of earth dams and tall embankments. The methodology is based on ... -
Parametric investigation of lateral spreading of gently sloping liquefied ground
Valsamis, A. I.; Bouckovalas, G. D.; Papadimitriou, A. G. (2010)This paper investigates the main parameters affecting the anticipated maximum surface displacements due to earthquake-induced lateral spreading of mildly sloping ground. The main tool used for this purpose is a numerical ... -
Sand fabric evolution effects on drain design for liquefaction mitigation
Bouckovalas, G. D.; Papadimitriou, A. G.; Niarchos, D. G.; Tsiapas, Y. T. (2011)This paper revisits the seminal work of Seed and Booker (1977) [21] on the design of infinitely permeable drains for liquefaction mitigation. It is shown that their basic mathematical assumption for the rate of earthquake-induced ... -
