  • Parametric study of seismic pounding between RC buildings with aligned slabs 

    López Almansa, Francisco; Kharazian, Alireza (Elsevier, 2019-10-01)
    Article
    Restricted access - publisher's policy
    This paper presents a parametrical study on seismic pounding between pairs of RC frames with 3 and 5 stories and aligned slabs. The performance indices are the maximum inter-story drift, absolute acceleration, and story ...

  • Efficient aeroelastic analysis of inflatable structures using enhanced potential flow aerodynamics 

    Ortega, Enrique; Flores Le Roux, Roberto Maurice; Cuartero Zaragoza, Eric; Oñate Ibáñez de Navarra, Eugenio (2019-10)
    Article
    Restricted access - publisher's policy
    An efficient method for the aeroelastic analysis of wind effects on inflatable structures is presented. The solution scheme is staggered and uses an explicit finite-element structural solver and potential flow aerodynamics. ...

    Article
    Open Access
    El artículo revindica el valor de los métodos de cálculo que se enseñan en las Escuelas de Ingeniería, como herramientas indispensables en los nuevos sistemas de ayuda a la toma de decisiones (SAD). Los SAD integran base ...

  • A finite point method for compressible flow 

    Löhner, Rainald; Sacco Giqueaux, Carlos Gustavo; Oñate Ibáñez de Navarra, Eugenio; Idelsohn Barg, Sergio Rodolfo (John Wiley & sons, 2002-03)
    Article
    Open Access
    A weighted least squares finite point method for compressible flow is formulated. Starting from a global cloud of points, local clouds are constructed using a Delaunay technique with a series of tests for the quality of ...

    Article
    Open Access
    Se presentan en este artículo unas reflexiones sobre los métodos numéricos, su evolución y la problemática que plantea su aplicación a problemas de ingeniería real, es decir en la práctica profesional del ingeniero. Se ...

  • Improving the structural reliability of steel frames using posttensioned connections 

    Bojórquez Mora, Edén; López Barraza, Arturo; Reyes Salazar, Alfredo; Ruiz Gómez, Sonia Elda; Ruiz García, Jorge; Formisano, Antonio; López Almansa, Francisco; Carrillo León, Julián; Bojórquez Mora, Juan (2019-01-01)
    Article
    Open Access
    In this paper, various moment-resisting steel frames (MRSFs) are subjected to 30 narrow-band motions scaled at different ground motion intensity levels in terms of spectral acceleration at first mode of vibration in order ...

  • Improved dynamical particle swarm optimization method for structural dynamics 

    Annicchiarico, W. C.; Cerrolaza Rivas, Miguel Enrique (2019-06)
    Article
    Open Access
    A methodology to the multiobjective structural design of buildings based on an improved particle swarm optimization algorithm is presented, which has proved to be very efficient and robust in nonlinear problems and when ...

  • Lagrangian analysis of multiscale particulate flows with the particle finite element method 

    Oñate Ibáñez de Navarra, Eugenio; Celigueta Jordana, Miguel Ángel; Latorre Sánchez, Juan Salvador; Casas González, Guillermo; Rossi, Riccardo; Rojek, Jerzy (Springer, 2014-05)
    Article
    Open Access
    We present a Lagrangian numerical technique for the analysis of flows incorporating physical particles of different sizes. The numerical approach is based on the particle finite element method (PFEM) which blends concepts ...

  • Advances in particle packing algorithms for generating the medium in the Discrete Element Method 

    Recarey Morfa, Carlos Alexander; Pérez, Irvin; Roselló, Roberto; Muniz de Farias, Márcio; Hernández Zubeldia, Elizabeth; Giraldo, Robinson; Oñate Ibáñez de Navarra, Eugenio (2019-03)
    Article
    Restricted access - publisher's policy
    Several theoretical contributions in order to establish a particle packing methodology are presented. In this respect, a generic formulation of a new method for packing particles based on a constructive advancing front ...

  • A cut finite element method for the solution of the full-potential equation with an embedded wake 

    Davari, Masud; Rossi, Riccardo; Dadvand, Pooyan; Lopez, Iñigo; Wüchner, Roland (Springer, 2019-05)
    Article
    Open Access
    Potential flow solvers represent an appealing alternative for the simulation of non-viscous subsonic flows. In order to deliver accurate results, such techniques require prescribing explicitly the so called Kutta condition, ...

  • A stabilized mixed implicit Material Point Method for non-linear incompressible solid mechanics 

    Iaconeta, Ilaria; Larese De Tetto, Antonia; Rossi, Riccardo; Oñate Ibáñez de Navarra, Eugenio (Springer, 2019-06)
    Article
    Restricted access - publisher's policy
    In this work a stabilized mixed formulation for the solution of non-linear solid mechanics problems in nearly-incompressible conditions is presented. In order to deal with high material deformation, an implicit Material ...
