    The statistical relationship between parameters that represent the intensity of ground motions induced by earthquakes (Intensity Measures, IM) and the nonlinear response of buildings (Engineering Demand Parameters, EDP) ...
  • Attention-based deep recurrent neural network to forecast the temperature behavior of an electric arc furnace side-wall 

    Godoy Rojas, Diego F.; León Medina, Jersson Xavier; Rueda, Bernardo; Vargas, Whilmar; Romero, Juan; Pedraza, Cesar; Pozo Montero, Francesc; Tibaduiza Burgos, Diego Alexander (Multidisciplinary Digital Publishing Institute (MDPI), 2022-02-12)
    Article
    Open Access
    Structural health monitoring (SHM) in an electric arc furnace is performed in several ways. It depends on the kind of element or variable to monitor. For instance, the lining of these furnaces is made of refractory materials ...
  • Novel seismic design solution for underground structures. Case study of a 2-story 3-bay subway station 

    Bu, Xiangbo; Ledesma Villalba, Alberto; López Almansa, Francisco (Elsevier, 2022-02)
    Article
    Open Access
    This paper proposes an innovative seismic design approach for shallow rectangular cut-and-cover underground subway or railway stations. The traditional approach is to design rigid frame-like structures by connecting rigidly ...
  • Data classification methodology for electronic noses using uniform manifold approximation and projection and extreme learning machine 

    León Medina, Jersson Xavier; Parés Mariné, Núria; Anaya Vejar, Maribel; Tibaduiza Burgos, Diego Alexander; Pozo Montero, Francesc (Multidisciplinary Digital Publishing Institute (MDPI), 2021-12-22)
    Article
    Open Access
    The classification and use of robust methodologies in sensor array applications of electronic noses (ENs) remain an open problem. Among the several steps used in the developed methodologies, data preprocessing improves the ...
  • Manifold learning algorithms applied to structural damage classification 

    León Medina, Jersson Xavier; Anaya Vejar, Maribel; Tibaduiza Burgos, Diego Alexander; Pozo Montero, Francesc (2021-06-05)
    Article
    Open Access
    A comparative study of four manifold learning algorithms was carried out to perform the dimensionality reduction process within a proposed methodology for damage classification in structural health monitoring (SHM). Isomap, ...

    León Medina, Jersson Xavier; Anaya Vejar, Maribel; Parés Mariné, Núria; Tibaduiza Burgos, Diego Alexander; Pozo Montero, Francesc (Multidisciplinary Digital Publishing Institute (MDPI), 2021-04-13)
    Article
    Open Access
    Damage classification is an important topic in the development of structural health monitoring systems. When applied to wind-turbine foundations, it provides information about the state of the structure, helps in maintenance, ...
  • A simplified approach to account for directionality effects on 2D dynamic soil-structure interaction analysis 

    Pinzón Ureña, Luis; Pujades Beneit, Lluís; Alva Bañuelos, Rodrigo Esteban; Mánica Malcom, Miguel Ángel (CRC Press, 2019)
    Conference report
    Restricted access - publisher's policy
    In this study, a simplified approach to account for directionality effects on twodimensional (2D) dynamic soil-structure interaction analyses (DSSI) is proposed. When an earthquake is recorded, the direction with the maximum ...
  • Acquisition and processing of buildings’ vibrations using a Real-Aperture Radar, a non-invasive method 

    Alva Bañuelos, Rodrigo Esteban; González Drigo, José Ramón; Luzi, Guido; Pinzón Ureña, Luis; Pujades Beneit, Lluís (2018)
    Conference report
    Restricted access - publisher's policy
    In this paper, a simplified non-invasive method to diagnose the safety state of buildings is tested. The method is based in remote sensing measurements of the natural vibrations of actual buildings using an interferometric ...
  • New capacity and energy based damage index 

    Díaz, Sergio Alberto; Pujades Beneit, Lluís; Barbat Barbat, Horia Alejandro; Vargas Alzate, Yeudy Felipe; González Drigo, José Ramón; Alva Bañuelos, Rodrigo Esteban (2018)
    Conference report
    Open Access
    Non-linear dynamic analysis and the damage index of Park-Ang have been often used to assess expected seismic damage to a structure. Depending on the size of the structure and the duration of the record, the computational ...
  • Comparison among design solutions for precast buildings in medium-to-moderate seismicity zones 

    Eskubi Ugarte, Juan Ignacio; López Almansa, Francisco (World Conference on Earthquake Engineering, 2021)
