Energy geostructures: anew era for geotechnical engineering practice.

Lyesse Laloui, Melis Sütman

Energy geostructuresprovide low carbon, cost-effective and local energy solutions to structures and infrastructures, which opens a new era for the geotechnical engineering practice, by extending the conventional role of geotechnicaldesign to the one of add ...

Impact of Mineralogical Composition on Geotechnical Properties of Opalinus Clay

Lyesse Laloui, Alessio Ferrari, Eleonora Crisci

Opalinus Clay is the selected host geomaterial for the construction of underground geological disposals for radioactive waste in Switzerland. The formation has been studied in several sites, i.e. the Mont Terri laboratory, and several boreholes in the nort ...

Steel Columns under Multi-Axis Seismic Loading: Experimental Findings and Design Recommendations

Dimitrios Lignos, Ahmed Mohamed Ahmed Elkady

This paper summarizes the findings of two test programs that investigated the hysteretic behavior of wide-flange columns in steel moment-resisting frames. Both deep and shallow steel columns were examined. The members were subjected to unidirectional and b ...

Chemical Influence of Pore Pressure on Brine Flow in Clay-Rich Material

Roman Makhnenko, Etienne André Cassini, Danila Mylnikov

Hydromechanical properties of shales are complex due to the involved ma-terial structure, with the solid matrix being mainly formed by swelling clays and porosity dominated by nanometer scale tortuous voids with large aspect ratios. Intrinsic permeability ...
