    Article
    Restricted access - publisher's policy
    This paper presents a consistent and transparent methodology for the prioritisation of the pipeline sections to be renewed in the whole Aigües de Barcelona (AB) urban water network. The prioritisation index for pipeline ...

  • Condition assessment of building façades based on hazard to people 

    Ruiz Gorrindo, Félix; Aguado de Cea, Antonio; Serrat Piè, Carles; Casas Rius, Joan Ramon (2019-06)
    Article
    Restricted access - publisher's policy
    To make periodic inspections of the buildings is useful to quantify the extent to which deficiencies are severe or not, in order to facilitate decision making and prioritize interventions. In previous works by the authors ...

  • Structural system identification by measurement error-minimizing observability method 

    Lei, Jun; Lozano Galant, José Antonio; Xu, Dong; Turmo Coderque, José (John Wiley & sons, 2019-10)
    Article
    Restricted access - publisher's policy
    This paper proposes a method for the finite element model updating using static load tests under the framework of observability analysis. Previous works included measurement errors in the coefficient matrix of the observability ...

  • Self-sensing concrete made from recycled carbon fibres 

    Segura Pérez, Ignacio; Faneca Llesera, Gerard; Torrents Dolz, Josep M.; Aguado de Cea, Antonio (2019-10)
    Article
    Restricted access - publisher's policy
    The electrical and piezo-resistive responses of recycled carbon fibre (rCF)-reinforced concrete is analysed in this article. Two different PAN-based rCFs (monofilament rCF and fibrillated rCF sheets) incorporated into dry ...

  • Shear crack pattern identification in concrete elements via distributed optical fibre grid 

    Rodríguez Gutiérrez, Gerardo; Casas Rius, Joan Ramon; Villalba Herrero, Sergi (2019-12)
    Article
    Restricted access - publisher's policy
    An experimental methodology to obtain the shear cracking pattern in concrete elements is presented. The method is based on the use of Distributed Optical Fiber Sensors (DOFS) connected to an Optical Backscattered Reflectometer ...

  • Sustainability assessment of trenches including the new eco-trench: a multi-criteria decision-making tool 

    Casanovas Rubio, Maria del Mar; Pujadas Álvarez, Pablo; Pardo Bosch, Francesc; Blanco Álvarez, Ana; Aguado de Cea, Antonio (2019-11)
    Article

    Narrow trenches are a common technique for the installation of utility pipelines of small diameter. Theexcavated soil is not always appropriate as landfill and, in those cases, an appropriate soil from some-where else (ex. ...

  • Influence of the polymer structure of polycarboxylate-based superplasticizers on the intercalation behaviour in montmorillonite clays 

    Borralleras, Pere; Segura Pérez, Ignacio; Garcia Aranda, Miguel Angel; Aguado de Cea, Antonio (Elsevier, 2019-09)
    Article
    Restricted access - publisher's policy
    The influence of polymeric structure of polycarboxylate-ether (PCE) based superplasticizers on the intercalation behavior in sodium montmorillonite clay (Na-MNT) is investigated by performing in-situ X-ray diffraction ...

  • Shear crack width assessment in concrete structures by 2D distributed optical fiber 

    Rodríguez, Gerardo; Casas Rius, Joan Ramon; Villalba Herrero, Sergi (Elsevier, 2019-09)
    Article
    Restricted access - publisher's policy
    This paper outlines the second part of an experimental study to show the capabilities of distributed optical fiber sensors (DOFS) in their application to the structural health monitoring (SHM) of the shear performance of ...

  • Fatigue performance of distributed optical fiber sensors in reinforced concrete elements 

    Barrias, Antonio; Casas Rius, Joan Ramon; Villalba Herrero, Sergi (Elsevier, 2019-09)
    Article
    Restricted access - publisher's policy
    In this paper, the authors present the results of a laboratory test where two reinforced concrete beams were instrumented with Distributed Optical Fiber Sensors (DOFS) to allow the monitoring g of strain in four different ...

  • Fibre distribution and tensile response anisotropy in sprayed fibre reinforced concrete 

    Segura Castillo, Luis; Pialarissi Cavalaro, Sergio Henrique; Goodier, Chris; Aguado de Cea, Antonio; Austin, Simon (2018-02)
    Article
    Open Access
    Sprayed steel fibre reinforced concrete (SSFRC) is a material that tends to present anisotropy, due to the action of the spraying process inducing preferential fibre orientation. Despite numerous applications worldwide ...

  • Expansions with different origins in a concrete dam with bridge over spillway 

    Blanco Álvarez, Ana; Pialarissi Cavalaro, Sergio Henrique; Segura Pérez, Ignacio; Segura Castillo, Luis; Aguado de Cea, Antonio (Elsevier, 2018-02)
    Article
    Restricted access - publisher's policy
    Concrete dams with expansions from different origins are rare and scarcely documented in the literature, therefore their study gains special interest. This study presents the case of a 62-year-old concrete dam with signs ...

  • Sustainability of column-supported RC slabs: fiber reinforcement as an alternative 

    Fuente Antequera, Albert de la; Casanovas Rubio, Maria del Mar; Pons Valladares, Oriol; Armengou, Jaume (2019-07)
    Article
    Open Access
    Fiber-reinforced concrete has been used in structures without any additional reinforcement when the design is determined by transient load stages (precast segments for tunnels), in elements with favorable boundary conditions, ...
