    • A new concrete plastic-damage model with an evolutive dilatancy parameter 

      Poliotti, Mauro; Bairán García, Jesús Miguel (Elsevier, 2019-04-04)
      Article
      Accés obert
      Typical plastic-damage models for concrete use a constant dilatancy parameter. On problems sensitive to confinement and shear softening, this parameter needs ad hoc calibration to fit experimental observations. This makes ...

    • Experimental comparison of two testing setups for characterizing the shear mechanical properties of masonry 

      Segura Domingo, Jorge; Bernat Masó, Ernest; Mendizábal Dinucci, Virginia Dolores; Pelà, Luca; Roca Fabregat, Pedro; Gil Espert, Lluís (Elsevier, 2021-09-08)
      Article
      Accés obert
      The prediction of the structural capacity of masonry buildings against lateral loads requires an accurate characterization of the masonry strength and the general response under shear stresses. The experimental determination ...

    • Geomechanical stability of the caprock during CO2 sequestration in deep saline aquifers 

      Vilarrasa Riaño, Víctor; Olivella Pastallé, Sebastià; Carrera Ramírez, Jesús (2011)
      Article
      Accés obert
      Sequestration of carbon dioxide (CO2) in deep saline aquifers has emerged as a mitigation strategy for reducing greenhouse gas emissions to the atmosphere. The large amounts of supercritical CO2 that need to be injected ...

    • Micro-scale continuous and discrete numerical models for nonlinear analysis of masonry shear walls 

      Petracca, Massimo; Pelà, Luca; Rossi, Riccardo; Zaghi, Stefano; Camata, Guido; Spacone, Enrico (2017-09)
      Article
      Accés obert
      A novel damage mechanics-based continuous micro-model for the analysis of masonry-walls is presented and compared with other two well-known discrete micro-models. The discrete micro-models discretize masonry micro-structure ...

    • Yielding of rockfill in relative humidity-controlled triaxial experiments 

      Alonso Pérez de Agreda, Eduardo; Romero Morales, Enrique Edgar; Ortega, Enrique (2016-06)
      Article
      Accés obert
      The paper reports the results of suction controlled triaxial tests performed on compacted samples of two well graded granular materials in the range of coarse sand-medium gravel particle sizes: a quartzitic slate and a ...
