    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)
    Conference report
    Restricted access - publisher's policy
    This paper compares, mainly in terms of construction cost and rapidity, two seismic-resisting systems for low-to-midrise precast buildings in moderate-to-medium seismicity zones (in Spain): (i) ordinary buildings accounting ...

  • Case study of a heavily damaged building during the 2016 MW 7.8 Ecuador earthquake: directionality effects in seismic actions and damage assessment 

    Pinzón Ureña, Luis; Pujades Beneit, Lluís; Medranda, Irving; Alva Bañuelos, Rodrigo Esteban (2021-02)
    Article
    Open Access
    In this work, the directionality effects during the MW 7.8 earthquake, which occurred in Muisne (Ecuador) on 16 April 2016, were analyzed under two perspectives. The first one deals with the influence of these effects on ...

  • Entropy indicators: an approach for low-speed bearing diagnosis 

    Sandoval Núñez, Diego Aníbal; Leturiondo, Urko; Vidal Seguí, Yolanda; Pozo Montero, Francesc (Multidisciplinary Digital Publishing Institute (MDPI), 2021-02-01)
    Article
    Open Access
    To increase the competitiveness of wind energy, the maintenance costs of offshore floating and fixed wind turbines need to be reduced. One strategy is the enhancement of the condition monitoring techniques for pitch bearings, ...

  • A strong-motion database of Costa Rica: 20 Yr of digital records 

    Moya-Fernandez, Aaron; Pinzón Ureña, Luis; Schmidt-Díaz, Victor; Hidalgo-Leiva, Diego; Pujades Beneit, Lluís (2020-11)
    Article
    Open Access
    In this article, we present a strong-motion database from earthquakes recorded by the Earthquake Engineering Laboratory at the University of Costa Rica. The database consists of 2471 three-component accelerograms from 155 ...

  • Application of manifold learning algorithms to improve the classification performance of an electronic nose 

    León Medina, Jersson Xavier; Anaya Vejar, Maribel; Pozo Montero, Francesc; Tibaduiza Burgos, Diego Alexander (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Conference report

    The problem of classification and the use of robust methodologies in electronic nose sensor arrays applications are still open. Among the several steps in the developed method- ologies, it is clear that feature extraction ...

  • Identificación no lineal de movimientos sísmicos en el lecho rocoso ingenieril a partir de registros tomados en la superficie 

    Rodríguez Sánchez, Julio; López Almansa, Francisco; Ledesma Villalba, Alberto (Asociación Chilena de Sismología e Ingeniería Antisísmica, 2019)
    Conference report
    Open Access
    En ingeniería sísmica, los registros disponibles suelen ser superficiales y, en consecuencia, los movimientos en las capas inferiores deben ser estimados conociendo el perfil estratigráfico del terreno; estos movimientos ...

  • Dynamic monitoring of a mid-rise building by real-aperture radar interferometer: advantages and limitations 

    Alva Bañuelos, Rodrigo Esteban; Pujades Beneit, Lluís; González Drigo, José Ramón; Luzi, Guido; Caselles Magallón, Josep Oriol; Pinzón Ureña, Luis (Multidisciplinary Digital Publishing Institute (MDPI), 2020-03)
    Article
    Open Access
    In this paper, remote and in situ techniques to estimate the dynamic response of a building to ambient vibration are reported: data acquired through a real-aperture radar (RAR) interferometer and conventional accelerometers ...

  • Increased seismic hazard in Barcelona (Spain) due to soil-building resonance effects 

    Pinzón Ureña, Luis; Pujades Beneit, Lluís; Macau, Albert; Figueras Vila, Sara (Elsevier, 2019-02)
    Article
    Open Access
    In this study, previous microzonation studies in Barcelona (Spain) were revisited, and available data on the predominant periods of soils in the city were compiled to develop an updated microzonation map of the city. In ...

  • An efficient method for considering the directionality effect of earthquakes on structures 

    Pinzón Ureña, Luis; Díaz Carrasco, Sergio; Pujades Beneit, Lluís; Vargas Alzate, Yeudy Felipe (2021-09)
    Article
    Open Access
    Recent research have proven the importance of considering the directionality effect on the expected seismic damage of structures. However, it demands a high computational effort if the nonlinear dynamic analysis (NLDA) is ...
