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'editorialThis 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 obertThe 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 obertA 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'editorialIn 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 obertThis 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 ...
