Fault reactivation during fluid pressure oscillations: transition from stable to unstable slip

Marie Estelle Solange Violay, François Xavier Thibault Passelègue, Carolina Giorgetti, Corentin Jean-Marie Rémi Noël

High‐pressure fluid injection in deep geo‐reservoirs can induce earthquakes. Recent observations suggest that cyclic injections might trigger less seismicity than monotonic injections. Here, we report triaxial laboratory experiments conducted on faulted qu ...

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 ...

Effect of dilatancy on the transition from aseismic to seismic slip due to fluid injection in a fault

Brice Tanguy Alphonse Lecampion, Federico Ciardo

Aseismic crack growth upon activation of fault slip due to fluid injection may or may not lead to the nucleation of a dynamic rupture depending on in-situ conditions, frictional properties of the fault and the value of overpressure. In particular, a fault ...

Micromechanical controls of mixed-mode anticrack nucleation in porous solids: application to snow failure

Johan Alexandre Philippe Gaume, Henning Löwe, Jonas Ritter

Porous cohesive materials can fail and collapse under compressive stresses. This mechanical behavior is generally referred to as anticrack and in snow, it is at the origin of catastrophic avalanches. In this study, we investigate how the microstructure of ...

Universal features of anticrack nucleation in porous solids

Johan Alexandre Philippe Gaume, Henning Löwe, Jonas Ritter

Characterizing the nucleation of anticracks in porous materials under compression is a great challenge and has been the subject of several investigationsin different fields, from earthquake science, rock mechanics to avalanche research[1]. Yet, the conditi ...

Exposed Column Base Connections for Minimizing Earthquake-induced Residual Deformations in Steel Moment-Resisting Framess

Dimitrios Lignos, Albano António De Abreu E Presa De Castro E Sousa, Hiroyuki Inamasu

This paper proposes a new exposed column base (XCB) design concept for steel moment-resisting frames (MRFs) that promotes anchor rod yielding rather than plastic hinging at the bottom of the first story columns. A mechanics-based numerical model is first d ...

Experimental investigation on the deformation capacity of lap splices under cyclic loading

Katrin Beyer, João Saraiva Esteves Pacheco de Almeida, Danilo Tarquini

Correct detailing and positioning of lap splices is essential in order to prevent premature failure of reinforced concrete structural members. Especially before the introduction of capacity design guidelines, lap splices were often placed in member regions ...

Behavior of iron-based Shape Memory Alloys under Cyclic Loading Histories

Dimitrios Lignos, Albano António De Abreu E Presa De Castro E Sousa, Diego Isidoro Heredia Rosa, Masoud Motavalli, Alexander Riley Hartloper

Shape memory alloys (SMAs) have gained considerable attention in a broad range of engineering applications. In particular, iron-based SMAs (Fe-SMAs) have been recently developed and used as a cost-effect method for prestressed-strengthening of civil struct ...
