Article
In the study of liquefaction potential, most researchers have focused on clean sand. Reports from studies on silty sand and silt are rare; thus, different aspects of the subject are not well known. The present investigation uses cyclic triaxial tests, the effect of factors such as the cyclic stress ratio (CSR), and the non-plastic finegrained soil...
Article
The paper studies the response of a 3-storey building subjected to reverse faulting. 1 g physical model tests are conducted using a 3 m long split-box, modelling the nonlinear response of structural members with artificial plastic hinges. The experimental results are used to validate the numerical modelling technique, which is subsequently employed...
Article
The paper studies the interaction of buried pipelines with a reverse fault rupture, employing 3D finite element (FE) modelling. A thoroughly validated strain softening constitutive model is employed to conduct a parametric study, exploring the effect of sediment thickness, pipeline burial depth, and thickness. It is shown that the increase of sedim...

This research explores the effectiveness of the use of stiff diaphragm walls next to a rocking foundation through numerical simulation. This improvement technique is used as a means to increase in subsoil peripheral confinement and reduce rocking-induced settlement. The numerical model was verified by the centrifuge test of rocking shallow foundati...

Recent major earthquakes (Italy 2016, Wenchuan 2008, Chi-Chi 1999) have offered numerous examples of fault rupture interaction with structures. In most previous studies, the superstructure was modeled in a simplified manner. This paper studies the interaction of a reverse fault rupture with a 3-story building modeled in adequate detail. For this pu...

Buried pipelines have become essential parts of lifelines and usually pass from large geographical regions. Therefore, they could be subjected to different types of hazards caused by wave propagation and/or permanent ground deformation along their path. Recent earthquakes have shown wide ranges of damages applied to pipelines in case of reverse fau...
Conference Paper
Full-text available
As pipelines pass from large geographical regions, their passage through areas with active faults in seismic regions might be inevitable. On the other hand, map of active faults is faced with many uncertainties and it is not possible to estimate the precise place of fault, angle of fault and the fault line. Thus, as lifelines, pipelines are vulnera...
Article
Recent major seismic events, such as the Chi-Chi (1999) and the Wenchuan (2008) earthquakes occurred in Taiwan and China, have offered a variety of case histories on the performance of structures subjected to reverse faulting–induced deformation. A novel faulting mitigation method has recently been proposed, introducing a soft deformable wall barri...
Conference Paper
Full-text available
Due to the damages of many structures like buildings, bridges, dams, tunnels and etc., by the permanent relative displacement of surface fault, it is too important to investigate fault rupture propagation. The occurrence of three tremendous earthquakes of 1999 in Turkey and Taiwan was the start of a comprehensive study of the fault rupture propagat...
Article
Full-text available
During past earthquakes, many instances of building damage as a result of earthquake surface fault rupture have been observed. The results of investigating a potential mitigation scheme are presented in this paper. Such plan provides a wall in the soil with the aim of surface displacement localization in the narrow pre-determined location. This may...
Article
Full-text available
When seismic thrust faults emerge on the ground surface, they are particularly damaging to buildings, bridges and lifelines that lie on the rupture path. To protect a structure founded on a rigid raft, a thick diaphragm-type soil bentonite wall (SBW) is installed in front of and near the foundation, at sufficient depth to intercept the propagating...
Conference Paper
Full-text available
One of the methods to enhance the seismic safety of existent embankment dams which may suffer from deficient stability against earthquake is application of additional slope at downstream. The traditional design approach of embankment dams for earthquake loading is based on limit equilibrium analysis with a horizontal pseudo-static seismic force app...
