  • An isolation device for near-fault ground motions 

    Abdel Kareem Moustafa, Mohamed Ismail; Rodellar Benedé, José; Pozo Montero, Francesc (2013-04)
    Article

    Seismic isolation is an appreciable control strategy that reduces the vibrations of structural and nonstructural systems induced by strong ground motions. However, under near-fault (NF) ground motion, the seismic isolation ...
  • Characterization, modeling and assessment of Roll-N-Cage isolator using the cable-stayed bridge benchmark 

    Abdel Kareem Moustafa, Mohamed Ismail; Rodellar Benedé, José; Carusone, Gennaro; Domaneschi, Marco; Martinelli, Luca (2013-03)
    Article

    This paper presents the results of an extensive series of simulation tests to identify the mechanical characteristics of an innovative isolation device known as the Roll-N-Cage (RNC) isolator. The seismic performance of ...
  • Hybrid RNC-isolation of structures under near-fault earthquakes 

    Abdel Kareem Moustafa, Mohamed Ismail; Pozo Montero, Francesc; Rodellar Benedé, José (2012)
    Conference lecture
    Open Access
    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 hybrid pounding mitigation of RNC-isolated structures 

    Abdel Kareem Moustafa, Mohamed Ismail; Pozo Montero, Francesc; Rodellar Benedé, José (2011)

  • 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
    Restricted access - publisher's policy
    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)
    Conference lecture
    Open Access
    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
    Restricted access - publisher's policy
    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
    Restricted access - publisher's policy
    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. ...
