  • Sustainability based-approach to determine the concrete type and reinforcement configuration of TBM tunnels linings. Case study: Extension line to Barcelona Airport T1 

    Fuente Antequera, Albert de la; Blanco Álvarez, Ana; Armengou, Jaume; Aguado de Cea, Antonio (2017-01)
    Article
    Accés restringit per política de l'editorial
    Fibre-reinforced concrete (FRC) is a suitable alternative to the traditional reinforced concrete used in the manufacture of precast segments used to line tunnels excavated with a tunnel boring machine (TBM). Moreover, its ...
  • Influence of fiber properties on the inductive method for the steel-fiber-reinforced concrete characterization 

    Juan-García, Pablo; Torrents Dolz, Josep M.; López Carreño, Rubén-Daniel; Pialarissi Cavalaro, Sergio Henrique (2016-08-01)
    Article
    Accés obert
    The inductive method has shown to be a good method for the estimation of fiber dosage in steel-fiber-reinforced concrete. The current formulations reported a strong correlation between inductance and fiber content, as well ...
  • Parameters controlling early age hydration of cement pastes containing accelerators for sprayed concrete 

    Salvador, Renan; Pialarissi Cavalaro, Sergio Henrique; Cincotto, Maria Alba; Domingues de Figueiredo, Antonio (2016-11)
    Article
    Accés restringit per política de l'editorial
    The objective of this work is to parametrize the early age hydration behavior of accelerated cement pastes based on the chemical properties of cement and accelerators. Eight cements, three alkali-free and one alkaline ...
  • Discrete element modelling of the fresh state behavior of pervious concrete 

    Pieralisi, Ricardo; Pialarissi Cavalaro, Sergio Henrique; Aguado de Cea, Antonio (2016-12)
    Article
    Accés restringit per política de l'editorial
    The objective of this paper is to propose a novel numerical approach to evaluate the fresh state behavior of pervious concrete (PC). A new constitutive law applied to Discrete Element Method was developed for the simulation ...
  • The wetting water in cement-based materials: modeling and experimental validation 

    Klein, Nayara Soares; Pialarissi Cavalaro, Sergio Henrique; Aguado de Cea, Antonio; Segura Pérez, Ignacio; Toralles Carbonari, Berenice Martins (2016-09)
    Article
    Accés restringit per política de l'editorial
    The physical role of water in cement-based materials is observed through the wetting of the grains, the need to fill the voids between particles and to separate these particles from one another, providing fluidity. The ...
  • Shear behaviour of sprayed concrete 

    García Vicente, Tomàs; Blanco Álvarez, Ana; Pialarissi Cavalaro, Sergio Henrique (2016-10)
    Article
    Accés restringit per política de l'editorial
    Shear in sprayed concrete (SC) may govern the design criteria in certain applications subjected to seismic loads or in bolted areas. However, it has been scarcely studied given the complexity of reproducing the production ...
  • Influence of the type of fiber on the structural response and design of FRC slabs 

    Blanco Álvarez, Ana; Pujadas Álvarez, Pablo; Fuente Antequera, Albert de la; Pialarissi Cavalaro, Sergio Henrique; Aguado de Cea, Antonio (2016-09)
    Article
    Accés obert
    Most codes for the design of fiber reinforced concrete (FRC) structures are based on the experience achieved throughout the years with steel fibers. Recent codes include the possibility of applying the same considerations ...
  • Solving some special cases of monomial ratio equations appearing frequently in physical and engineering problems 

    Castillo Ron, Enrique; Nogal Macho, María; Lozano Galant, Jose Antono; Turmo Coderque, José (2016)
    Article
    Accés obert
    We first show that monomial ratio equations are not only very common in Physics and Engineering, but the natural type of equations in many practical problems. More precisely, in the case of models involving scale variables ...
  • Active control implementation in cable-stayed bridges for quasi-static loading patterns 

    Crusells Girona, Miquel; Aparicio Bengoechea, Ángel Carlos (2016-07)
    Article
    Accés restringit per política de l'editorial
    The following paper deals with active control implementation in cable-stayed bridges. Recent developments in structural active control of cable-stayed bridges are focused on the adaptability to dynamic effects produced by ...
  • Sustainability as the key to prioritize investments in public infrastructures 

    Pardo Bosch, Francesc; Aguado de Cea, Antonio (2016-09)
    Article
    Accés restringit per política de l'editorial
    Infrastructure construction, one of the biggest driving forces of the economy nowadays, requires a huge analysis and clear transparency to decide what projects have to be executed with the few resources available. With the ...
