    • Hybrid RNC-isolation of structures under near-fault earthquakes 

      Abdel Kareem Moustafa, Mohamed Ismail; Pozo Montero, Francesc; Rodellar Benedé, José (2012)
      Comunicació de congrés
      Accés obert
      The problem of combining active damping with a purely passive isolation system, with hysteretic damping,to reduce possible pounding effects under near-fault ground motions is addressed. The used isolation system is a ...

    • Near-fault isolation of cable-stayed bridges using RNC isolator 

      Abdel Kareem Moustafa, Mohamed Ismail; Casas Rius, Joan Ramon; Rodellar Benedé, José (2013-11)
      Article
      Accés restringit per política de l'editorial
      This paper investigates the near-fault (NF) seismic performance of a recent isolation system, referred to as Roll-N-Cage (RNC) isolator, considering the cable-stayed Bill Emerson Memorial Bridge in Missouri, USA. Under NF ...

    • Numerical characterization of RNC isolator experimental prototypes 

      Abdel Kareem Moustafa, Mohamed Ismail; Rodellar Benedé, José (2011)
      Comunicació de congrés
      Accés obert
      The results of an extensive series of numerical simulation tests to identify the mechanical characteristics of the recently proposed roll-n-cage (RNC) isolation bearing are presented. Several different configurations of ...

    • Passive and hybrid mitigation of potential near-fault inner pounding of a self-braking seismic isolator 

      Abdel Kareem Moustafa, Mohamed Ismail; Rodellar Benedé, José; Pozo Montero, Francesc (2015-02-01)
      Article
      Accés obert
      A seismic isolated structure is usually a long-period structural system, which may encounter a low-frequency resonance problem when subjected to a near-fault earthquake that usually has a long-period pulse-like waveform. ...

    • Performance of structure-equipment systems with a novel roll-n-cage isolation bearing 

      Abdel Kareem Moustafa, Mohamed Ismail; Rodellar Benedé, José; Ikhouane, Fayçal (2009-12)
      Article
      Accés restringit per política de l'editorial
      In this the paper, the problem of mitigating the seismic response of sensitive equipments housed in building structures is addressed by isolating the structure with an innovative device referred to as roll-n-cage isolator. ...

    • Reduced-order coupled bidirectional modeling of the Roll-N-Cage isolator with application to the updated bridge benchmark 

      De Mari, G.; Domaneschi, Marco; Abdel Kareem Moustafa, Mohamed Ismail; Martinelli, Luca; Rodellar Benedé, José (2015-10-01)
      Article
      Accés obert
      This work presents and assesses a reduced model of a recently proposed seismic isolation system, namely the Roll-N-Cage isolator. This system incorporates several interesting features and mechanisms in a single unit, among ...
