    • Variability of the bond and mechanical properties of self-compacting concrete 

      Menezes de Almeida Filho, Fernando; Barragán, Bryan E.; Casas Rius, Joan Ramon; El Debs, Ana Lúcia H. C. (2008-03)
      Article
      Accés obert
      This main objective of this research is to evaluate the variability of the mechanical properties (compressive strength, modulus of elasticity and tensile strength) and bond strength of the self-compacting concrete (SCC), ...

    • Verificación experimental de uniones mediante lazos de armadura y su aplicación en la construcción evolutiva de puentes 

      Contreras, Catalina P.; Casas Rius, Joan Ramon; Aparicio Bengoechea, Ángel Carlos (Asociacion Científica del Hormigón Estructural (ACHE), 2011)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      El presente trabajo entrega un estudio a partir de ensayos de un nuevo tipo de empalme para puentes de sección cajón construidos evolutivamente, buscando reducir riesgos asociados a la construcción y plazos de ejecución. ...

    • Vibration based criteria for damage control in bridge structures 

      Rodrigues, J. Fernando; Almeida, Pedro A.O.; Casas Rius, Joan Ramon (2011)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Along the years, researchers have made efforts in the sense of quantifying structural performance and damage in function of vibration measurements, [1] and [2]. Similarly the present work investigates a vibration based ...

    • Vibration based damage detection techniques for small to medium span bridges: a review and case study 

      Moughty, John James; Casas Rius, Joan Ramon (2016)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Overtime, the structural condition of bridges tends to decline due to a number of degradation processes, such as; creep, corrosion and cyclic loading, among others. Considerable research has been conducted over the years ...

    • Vibration-based, output-only damage identification of bridge under vehicle induced excitation 

      Moughty, John James; Casas Rius, Joan Ramon (Civil Engineering Research Association of Ireland (CERAI), 2018)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Many traditional methods of damage identification in bridge structures implement numerical models and/or modal parameters as a means of condition assessment. While such techniques can often be effective, they may also ...

    • WIM-based live-load model for advanced analysis of simply supported short- and medium-span highway bridges 

      Anitori, Giorgio; Casas Rius, Joan Ramon; Ghosn, Michel (2017-10)
      Article
      Accés obert
      The accuracy of bridge system safety evaluations and reliability assessments obtained through refined structural analysis procedures depends on the proper modeling of traffic load effects. While the live-load models specified ...
