  • Importance of non-simulated failure modes in incremental dynamic analysis (IDA) of non-ductile RC frames 

    López Almansa, Francisco; Alfarah, Bashar; Oller Martínez, Sergio Horacio (International Association for Earthquake Engineering, 2017)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Nonlinear dynamic analysis of reinforced concrete structures requires a thorough understanding of behavior of structural elements for all levels of performance, especially collapse. Main reason is that reinforced concrete ...
  • Seismic damage assessment of URM buildings: a comparison of non-linear static procedures 

    González Drigo, José Ramón; Ávila Haro, Jorge Arturo; Pujades Beneit, Lluís; Barbat Barbat, Horia Alejandro (2016)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    In the scientific literature, a significant number of non-linear procedures are proposed in order to evaluate the seismic vulnerability of a building. In this work, and in the context of the Risk-UE methodology, a complete ...
  • Capacity curve based damage index for steel buildings: a probabilistic approach 

    Díaz-Alvarado, S.A.; Pujades Beneit, Lluís; Barbat Barbat, Horia Alejandro; Hidalgo-Leiva, D.A.; Vargas Alzate, Yeudy Felipe (2016)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    The capacity and expected seismic damage of several types of steel buildings are assessed by using a probabilistic approach. Nonlinear static and dynamic analyses are performed by means of Monte Carlo Simulations. Concerning ...
  • Evaluation of seismic damage in low-rise buildings of reinforced concrete masonry 

    Hidalgo-Leiva, D.A.; Pujades Beneit, Lluís; Barbat Barbat, Horia Alejandro; Díaz-Alvarado, S.A.; Vargas Alzate, Yeudy Felipe (2016)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    The assessment of damage caused by earthquakes in structures, requires the use of nonlinear analysis, either static or dynamic, in order to define the performance of the buildings for the considered hazard levels. In this ...
  • New parametric model for capacity curves and a new capacity based damage index 

    Pujades Beneit, Lluís; Vargas Alzate, Yeudy Felipe; Barbat Barbat, Horia Alejandro; González Drigo, José Ramón; Díaz-Alvarado, S.A.; Hidalgo-Leiva, D.A. (2016)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    A recently proposed parametric model re-conceptualizes capacity curves as composed by linear and non-linear parts. The normalized non-linear capacity curve can be modelled by a cumulative lognormal function. While the ...
  • Seismic assessment of high-rise URM buildings: a probabilistic approach 

    Ávila Haro, Jorge Arturo; González Drigo, José Ramón; Pujades Beneit, Lluís; Barbat Barbat, Horia Alejandro (2016)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    The definition of the seismic demand and the correct characterization of the mechanical properties of the materials are two of the major difficulties in the seismic damage assessment of unreinforced masonry buildings due ...
  • A micromechanical approach to modeling the effect of impact induced damage on the vibration response of CFRP laminates 

    Pérez Martínez, Marco Antonio; Gil Espert, Lluís; Oller Martínez, Sergio Horacio; Felippa, Carlos (2015)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    This work deals with modeling the effect of low-velocity impact damage upon the vibration response of CFRP laminates through a micro-mechanical description of the induced internal damage. The serial-parallel (SP) continuum ...
  • On multi-scale structural topology optimization and material design 

    Ferrer Ferré, Àlex; Cante Terán, Juan Carlos; Oliver Olivella, Xavier (Associação Portuguesa de Mecânica Teórica, Aplicada e Computacional (APMTAC), 2015)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Computational material design has gained considerable interest, along the last years, in the computational mechanics community. Although most of the current approaches focus on one-scale structural optimization, this work ...
  • The concept of Representative Volume Elements for elastic, hardening and softening materials 

    Gitman, Inna M.; Askes, Harm; Sluys, Lambertus J.; Lloberas Valls, Oriol (2004)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    The concept of the Representative Volume Element (RVE) is analysed in the present paper. For elastic materials, one can determine the size of the RVE. However, for other applications, such as the case of softening materials, ...
