    Link elements are dissipative devices in form of beam segments that are typically included in eccentrically braced frames (EBF) subjected to lateral loads and seismic hazard. Studies related to short links, ...
  • A comparative analysis of longitudinal stiffener cross-section for slender I-girders subjected to patch loading 

    Chacón Flores, Rolando Antonio; Loaiza, Nelson; Graciano, Carlos; Casanova, Euro (Wilhelm Ernst & Sohn, 2017)

    En esta comunicación se presenta un método de diseño sísmico directo basado en prestaciones desarrollado para estructuras irregulares. Este método es una extensión del método de diseño no lineal estático; ambos, a través ...
  • Effects of axial forces and prestressing on the shear strength of structural concrete members 

    Marí Bernat, Antonio Ricardo; Cladera Bohigas, Antoni; Bairán García, Jesús Miguel (2017)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Axial forces affect the shear strength of concrete members. The estimation of such effects on the shear strength depends on how the axial force influences the various shear transfer mechanisms, since a very different ...
  • Assessment of the existing models to evaluate the shear strength contribution of externally bonded FRP reinforcements 

    Oller Ibars, Eva; KOTYNIA, RENATA; Marí Bernat, Antonio Ricardo; KASZUBSKA, Monika (2017)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    This paper presents a comparative analysis of the performance of some the existing formulations to evaluate the FRP contribution to the total shear strength of reinforced concrete beams strengthened in shear by externally ...
  • A new punching shear mechanical model for reinforced concrete slabs with and without punching reinforcement 

    Marí Bernat, Antonio Ricardo; Cladera Bohigas, Antoni; Ribas González, Carlos Rodrigo; Bairán García, Jesús Miguel; Oller Ibars, Eva (2017)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    A punching shear strength mechanical model for RC slabs with and w/o punching reinforcement, based on a previous shear model developed by the authors, is presented. The identified differences between shear and punching ...
