  • Seismic vulnerability of buildings: from intuition to evaluation 

    Barbat Barbat, Horia Alejandro; Salgado Gálvez, Mario Andrés; Carreño Tibaduiza, Martha Liliana; Cardona Arboleda, Omar Dario (Editura Universitaria Ion Mincu, 2016)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    In many seismic areas of the world, there are nowadays vulnerable structures, designed and built without seismic codes or using outdated codes. The seismic vulnerability of the buildings is, sometimes, not so difficult to ...
  • Advanced solid elements for sheet metal forming simulation 

    Mataix, Vicente; Rossi, Riccardo; Oñate Ibáñez de Navarra, Eugenio; Flores, Fernando G (Institute of Physics (IOP), 2016)
    Text en actes de congrés
    Accés obert
    The solid-shells are an attractive kind of element for the simulation of forming processes, due to the fact that any kind of generic 3D constitutive law can be employed without any additional hypothesis. The present work ...
  • Control of heat flux using computationally designed metamaterials 

    Fachinotti, Víctor D.; Peralta, Ignacio; Huespe, Alfredo Edmundo; Ciarbonetti, A. (2016)
    Text en actes de congrés
    Accés obert
    To gain control over the diffusive heat flux in a given domain, one has to design metamaterials with a specifc distribution of the generally anisotropic thermal conductivity throughout the domain. Until now, the appropriate ...
  • A macro-modelling finite element technique for the realistic simulation of cracking in masonry structures 

    Saloustros, Savvas; Pelà, Luca; Cervera Ruiz, Miguel; Roca Fabregat, Pedro (CRC Press, 2016)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    This paper presents an improved computational model for the analysis of masonry structures based on continuum mechanics finite element approaches. The proposed numerical technique uses a cracktracking algorithm to model ...
  • Crack path field and strain injection techniques in dynamic fracture simulations 

    Lloberas Valls, Oriol; Huespe, Alfredo Edmundo; Oliver Olivella, Xavier; Dias, I.F. (2016)
    Text en actes de congrés
    Accés obert
    Dynamic fracture phenomena are studied employing low cost computational tools based on Finite Elements with Embedded strong discontinuities (E-FEM). Fracture nucleation and propagation are accounted for through the injection ...
  • Latin American contributions to the GEM’s Earthquake Consequences Database 

    Cardona Arboleda, Omar Dario; Ordaz Schroeder, Mario Gustavo; Salgado Gálvez, Mario Andrés; Carreño Tibaduiza, Martha Liliana; Barbat Barbat, Horia Alejandro (2016)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    One of the projects of the Global Earthquake Model (GEM) was to develop a global earthquake consequences database (GEMECD) which served both to be an open and public repository of damages and losses on different types of ...
  • The holistic evaluation of the seismic risk for Manizales, Colombia 

    Carreño Tibaduiza, Martha Liliana; Cardona Arboleda, Omar Dario; Barbat Barbat, Horia Alejandro (2016)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    This article presents a methodology which evaluates the seismic risk from a holistic perspective, that is, it takes into account the expected physical damage and also the conditions related to social fragility and lack of ...
  • Effect of pier-spandrel geometry on the in-plane response of masonry structures 

    Saloustros, Savvas; Pelà, Luca; Cervera Ruiz, Miguel; Roca Fabregat, Pedro; D'Ayala, Dina (Taylor & Francis, 2016)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    This paper presents a numerical study on the effect of the relative geometry between piers and spandrels in the structural response of regular masonry frames against horizontal loading. A sensitivity analysis is carried ...
  • Advanced numerical techniques for modeling tensile crack propagation in gravity dams 

    Dias, I.F.; Oliver Olivella, Xavier; Lemos, J.V.; Lloberas Valls, Oriol (Laboratório Nacional de Engenharia Civil, 2015)
    Text en actes de congrés
    Accés obert
    Cracks propagating deep inside gravity dams can seriously affect their structural safety. Due to the potential catastrophic scenarios associated to the collapse of large concrete dams, it is a fundamental issue to ...
  • Numerical simulation of penetration problems in geotechnical engineering with the particle finite element method (PFEM) 

    Monforte Vila, Lluís; Carbonell Puigbó, Josep Maria; Arroyo Alvarez de Toledo, Marcos; Gens Solé, Antonio (Centre Internacional de Mètodes Numèrics en Enginyeria (CIMNE), 2015)
    Text en actes de congrés
    Accés obert
    This paper highlights a computational framework for the numerical analysis of saturated soil-structure interaction problems. The variational equations of linear momentum and mass balance are obtained for the large deformation ...
