Reduction of a Cone-Shaped Terrain Grounding Resistance by Remote Grounding

Tall structures such as wind turbines and mobile phone base stations are often installed in remote and hilly locations to gain more power or to have line of sight to end users. Those locations are usually very rocky and characterized by a low-conductivity ...

Isolated vs. Interconnected Wind Turbine Grounding Systems: Effect on the Harmonic Grounding Impedance, Ground Potential Rise and Step Voltage

Marcos Rubinstein, Antonio Sunjerga, Qi Li

Wind turbines are very vulnerable to lightning strikes due to their height, sharp edges and remote locations often with high soil resistivity. In this paper we present numerical simulations of the impedance of a typical wind turbine grounding geometry. We ...

Effective Stiffness and drift capacity of modern unreinforced masonry walls

Katrin Beyer, Bastian Valentin Wilding

Code design of unreinforced masonry (URM) buildings is based on elastic analysis, which requires as input parameter the effective stiffness and the ultimate drift capacity of the in-plane force-displacement response of URM walls. Eurocode 8, for example, e ...

A nodal discontinuous Galerkin finite element method for the poroelastic wave equation

Jan Sickmann Hesthaven, Khemraj Shukla

We use the nodal discontinuous Galerkin method with a Lax-Friedrich flux to model the wave propagation in transversely isotropic and poroelastic media. The effect of dissipation due to global fluid flow causes a stiff relaxation term, which is incorporated ...

Reservoir stimulation’s effect on depletion-induced seismicity

Lyesse Laloui, Barnaby Padraig Fryer, Gunter Siddiqi

Depletion-induced seismicity can pose a problem in some fluid-producing subsurface reservoirs, in some cases requiring production rate control in order to limit the seismicity. This study investigates the use of reservoir stimulation to reduce the depletio ...

One Dimensional Consolidation of Opalinus Clay from Shallow Depth

Lyesse Laloui, Alessio Ferrari, Eleonora Crisci

First experimental results on Opalinus Clay from shallow depth (< 30 m depth) are presented and compared to results on cores from Mont Terri Underground Rock Laboratory (~ 300 m depth). Samples were tested in one dimensional condition using an advanced exp ...

New method for measuring compressibility and poroelasticity coefficients in porous and permeable rocks

Lucas Xan Pimienta

Over the last decades, a large understanding has been gained on the elastic properties of rocks. Rocks are, however, porous materials, which properties depend on both response of the bulk material and of the pores. Because in that case both the applied ext ...

Displacement interaction among energy piles bearing on stiff soil strata

Lyesse Laloui, Alessandro Francesco Rotta Loria

This study presents an analysis of the displacement interaction among general configurations of energy piles bearing on stiff soil strata that are subjected to thermal loads. This work integrates recent analyses investigating the displacement interaction a ...
