      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 ...
    • 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 ...
    • Daño sísmico y propiedades modales en estructuras de edificación 

      Alva Bañuelos, Rodrigo Esteban (Universitat Politècnica de Catalunya, 2021-09-17)
      Doctoral thesis
      Open Access
      The time required to inspect damaged structures after an earthquake has a direct impact on the social and economic consequences of the event, which can be catastrophic. Developing tools to aid the inspection task is of ...
    • Do directionality effects influence expected damage? A case study of the 2017 central Mexico earthquake 

      Pinzón, Luis A.; Pujades Beneit, Lluís; Díaz, Sergio Alberto; Alva Bañuelos, Rodrigo Esteban (2018-10)
      Article
      Open Access
      We analyze the case of a building that collapsed in a multifamily complex of Tlalpan borough in Mexico City during the 19 September 2017 Central Mexico earthquake. Despite having similar materials and similar structural ...
    • 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 ...
    • Dynamic soil-structure interaction analyses considering directionality effects 

      Pinzón Ureña, Luis; Mánica Malcom, Miguel Ánge; Pujades Beneit, Lluís; Alva Bañuelos, Rodrigo Esteban (Elsevier, 2020-03)
      Article
      Open Access
      The paper investigates directionality effects of ground motions in the context of dynamic soil-structure interaction (DSSI) analyses. The problem addressed corresponds to a nonlinear soil deposit, overlaying firm ground, ...
    • 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 ...
    • On the equal displacement aproximation for mid-rise reinforced concrete buildings 

      Vargas Alzate, Yeudy Felipe; Pujades Beneit, Lluís; González Drigo, José Ramón; Alva Bañuelos, Rodrigo Esteban; Pinzón Ureña, Luis (Institute of Structural Analysis and Antiseismic Research School of Civil Engineering. National Technical University of Athens (NTUA), 2019)
      Conference report
      Open Access
      The equal displacement approximation is a well-known procedure for estimating the non-linear behavior of structures subjected to earthquake ground motions. This procedure plays a significant role in current seismic design, ...
    • Remote ambient vibration measurements with real aperture radar to estimate buildings dynamic properties 

      Alva Bañuelos, Rodrigo Esteban; González Drigo, José Ramón; Luzi, Guido; Caselles Magallón, Josep Oriol; Pujades Beneit, Lluís; Vargas Alzate, Yeudy Felipe; Pinzón Ureña, Luis (Institute of Structural Analysis and Antiseismic Research School of Civil Engineering.
