  • Numerical analysis of rapid drawdown: applications in real cases 

    Alonso Pérez de Agreda, Eduardo; Pinyol Puigmartí, Núria Mercè (2016-07)
    Article
    Accés obert
    In this study, rapid drawdown scenarios were analyzed by means of numerical examples as well as modeling of real cases with in situ measurements. The aim of the study was to evaluate different approaches available for ...
  • Shear design and assessment of reinforced and prestressed concrete beams based on a mechanical model 

    Marí Bernat, Antonio Ricardo; Bairán García, Jesús Miguel; Cladera Bohigas, Antoni; Oller Ibars, Eva (2016-10)
    Article
    Accés obert
    Safe and economical design and assessment of reinforced (RC) and prestressed concrete (PC) beams requires the availability of accurate but simple formulations which adequately capture the structural response. In this paper, ...
  • Slope stability in slightly fissured claystones and marls 

    Alonso Pérez de Agreda, Eduardo; Pinyol Puigmartí, Núria Mercè (2015-08)
    Article
    Accés obert
    The paper deals with the behavior of some characteristic soft rocks found in the Iberian Peninsula. In geological terms, they belong to Tertiary basins, the Keuper period and the Jurassic-Cretacic transition. The discussion ...
  • Urban seismic risk index for Medellín, Colombia, based on probabilistic loss and casualties estimations 

    Salgado Gálvez, Mario Andrés; Zuloaga Romero, Daniela; Velásquez Villada, Cesar Augusto; Carreño Tibaduiza, Martha Liliana; Cardona Arboleda, Omar Dario; Barbat Barbat, Horia Alejandro (2016-02)
    Article
    Accés restringit per política de l'editorial
    Medellín is the second largest city of Colombia with more than 2 million inhabitants according to the latest census and with more than 240,000 public and private buildings. It is located on an intermediate seismic hazard ...
  • A pseudo-compressible variational multiscale solver for turbulent incompressible flows 

    Yang, Liang; Badia, Santiago; Codina, Ramon (2016-12)
    Article
    Accés restringit per política de l'editorial
    In this work, we design an explicit time-stepping solver for the simulation of the incompressible turbulent flow through the combination of VMS methods and artificial compressibility. We evaluate the effect of the artificial ...
  • New tension-compression damage model for complex analysis of concrete structures 

    Paredes, Jairo A.; Oller Martínez, Sergio Horacio; Barbat Barbat, Horia Alejandro (American Society of Civil Engineers (ASCE), 2016-10)
    Article
    Accés obert
    A new damage model, based on continuum damage mechanics and simulating the opening, closing, and reopening of cracks in concrete using only one surface of discontinuity, is proposed in this article. The model complies with ...
  • Influence of time-dependent restrained strains in the shear response of RC frames 

    Santos Ferreira, Denise Carina; Bairán García, Jesús Miguel; Marí Bernat, Antonio Ricardo (2017-02)
    Article
    Accés restringit per política de l'editorial
    Time-dependent strains, when restrained, can lead to important tensile forces and damage, affecting, among other aspects, the shear response and ultimate load carrying capacity of shear-critical RC frames. This paper ...
  • 3D FEM model development from 3D optical measurement technique applied to corroded steel bars 

    Fernández Pérez, Ignasi; Bairán García, Jesús Miguel; Marí Bernat, Antonio Ricardo (2016-10-15)
    Article
    Accés restringit per política de l'editorial
    Understanding the mechanical effects of the corrosion pits on the steel surface requires an accurate definition of their geometry and distribution along the rebar. 3D optical measurement technique is used to obtain the ...
  • Assessing the joint impact of DNAPL source-zone behavior and degradation products on the probabilistic characterization of human health risk 

    Henri, Christopher Vincent; Fernández García, Daniel; De Barros, Felipe P.J. (Elsevier, 2016-02)
    Article
    Accés restringit per política de l'editorial
    The release of industrial contaminants into the subsurface has led to a rapid degradation of groundwater resources. Contamination caused by Dense Non-Aqueous Phase Liquids (DNAPLs) is particularly severe owing to their ...
  • The domain interface method in non-conforming domain decomposition multifield problemsdomain decomposition multifield problems 

    Lloberas Valls, Oriol; Cafiero, Mailhyn E.; Cante Terán, Juan Carlos; Ferrer Ferré, Àlex; Oliver Olivella, Xavier (2016-12)
    Article
    Accés obert
    The Domain Interface Method (DIM) is extended in this contribution for the case of mixed fields as encountered in multiphysics problems. The essence of the non-conforming domain decomposition technique consists in a ...
