Porosity evolution at the brittle-ductile transition in the continental crust: Implications for deep hydro-geothermal circulation

Marie Estelle Solange Violay, Mateo Alejandro Acosta, Michael Heap

Recently, projects have been proposed to engineer deep geothermal reservoirs in the ductile crust. To examine their feasibility, we performed high-temperature (up to 1000 degrees C), high-pressure (130 MPa) triaxial experiments on granite (initially-intact ...

Punching shear strength and behaviour of compact reinforced concrete footings

Aurelio Muttoni, Miguel Fernández Ruiz, João Tiago Ramos Bernardo de Santa Rita Simões

concrete footings with and without transverse reinforcement. Even though that punching shear failures have already been deeply investigated, there is still scanty experimental information on full-scale reinforced concrete footings failing in punching shear ...

A model of the western Laurentide Ice Sheet, using observations of glacial isostatic adjustment

Jean-Philippe Lucien Montillet

We present the results of a new numerical model of the late glacial western Laurentide Ice Sheet, constrained by observations of glacial isostatic adjustment (GIA), including relative sea level indicators, uplift rates from permanent GPS stations, contempo ...

Chemical Characterisation of Deep Earth Reservoirs

Hélène Marie Piet

Seismic imaging of the internal Earth has emphasized the inhomogeneity of its mantle. This interface layer of nearly 3000 km surrounding the central metallic core conducts heat released from the latter, which played a significant role in shaping the actual ...

Atmospheric and oceanic climate forcing of the exceptional Greenland ice sheet surface melt in summer 2012

Konrad Steffen

The NASA announcement of record surface melting of the Greenland ice sheet in July 2012 led us to examine the atmospheric and oceanic climatic anomalies that are likely to have contributed to these exceptional conditions and also to ask the question of how ...

Shear deformations of slender reinforced concrete walls under seismic loading

Katrin Beyer, Alessandro Dazio

Experimental results gained from quasi-static cyclic tests on 34 slender structural reinforced concrete walls available in the literature are used to examine the shear deformations for displacement demands in the inelastic range. Based on these results the ...

Poinçonnement symétrique des dalles en béton armé

Stefano Guandalini

Punching of reinforced concrete and prestressed slabs is usually a critical failure mode for the design and verification of structures such as flat slabs or bridge slabs. Although codes of practice propose several rules for common cases (usually with an em ...
