A-seismic fracture growth driven by fluid injection and remote nucleation of dynamic rupture in a weaker part of the fault

Brice Tanguy Alphonse Lecampion, Andreas Möri, Federico Ciardo

Induced (and triggered) seismicity following fluid injections at depth, is governed by pore pressure diffusion. Interestingly, recent studies yield unrealistically large values of diffusivity in order to explain the timing of the generated seismicity. We i ...

Dissolved Organic Nitrogen Production and Export by Meridional Overturning in the Eastern Subpolar North Atlantic

Bieito Fernandez Castro

Dissolved organic matter (DOM) is produced in the surface and exported towards the deep ocean, adding similar to 2 PgC/year to the global carbon export. Due to its central role in the Meridional Overturning Circulation, the eastern subpolar North Atlantic ...

Parametric analysis on punching shear resistance of reinforced concrete continuous slabs

Aurelio Muttoni, Beatrice Belletti

Punching shear resistance formulations provided by codes are usually calibrated on test results of isolated specimens that typically simulate the slab zone within the points of contraflexure around the column (hogging area). However, the behaviour of actua ...

A mechanically-based model of snow slab and weak layer fracture in the Propagation Saw Test

Johan Alexandre Philippe Gaume, Lorenzo Benedetti

Dry-snow slab avalanche release is the result of failure initiation in a weak snowpack layer buried below a cohesive snow slab, which is then followed by rapid crack propagation. The Propagation Saw Test (PST) is a field experiment which allows to evaluate ...

Testing turbulence theories in the ocean: insights from state-of-the-art observations

Andrea Cimatoribus

During the last decade, environmental flows have been measured with a growing set of instruments, which can now offer relatively high resolution in space and time. This growing amount of data can analysed following a "statistical approach to turbulence", r ...

Effect of Modeling Assumptions on the Earthquake-Induced Losses and Collapse Risk of Steel-Frame Buildings with Special Concentrically Braced Frames

Dimitrios Lignos, Seong-Hoon Hwang

This paper quantifies the collapse risk and earthquake-induced economic losses of steel-frame buildings with special concentrically braced frames designed in urban California. A probabilistic building-specific loss estimation methodology that can explicitl ...

Upstream-migrating bedforms in steep channels: an important contribution to sediment transport fluctuations?

Christophe Ancey, François Mettra

Possible causes of high sediment transport fluctuations observed in mountainous rivers are still not well understood. Several studies have linked these fluctuations with the presence of bedforms. However, upstream-migrating bedforms, that are similar in pr ...

LABORATORY EXPERIMENTS OF PULSED SUBAQEOUS SEDIMENT DENSITY FLOWS: INTERNAL STRATIFICATION AND LAYERING

Mário Jorge Rodrigues Pereira Da Franca, Carmelo Juez Jiménez, Mariangela Sfouni-Grigoriadou

This paper reports on an experimental study which focuses on reproducing small scale sediment density flows in a laboratory flume. The observations are aimed at improving the parametrization of the relations that govern the transition between different pha ...

Punching shear capacity of continuous slabs

Aurelio Muttoni, Miguel Fernández Ruiz, Jürgen Einpaul

Provisions for punching shear design of reinforced concrete slabs are usually calibrated on the basis of results from tests on isolated specimens that simulate the slab zone within the points of contraflexure around a column. However, the punching behavior ...
