  • Influence of time-dependent restrained strains in the shear response of RC frames 

    Santos Ferreira, Denise Carina; Bairán García, Jesús Miguel; Marí Bernat, Antonio Ricardo (2017-02)
    Article
    Accés restringit per política de l'editorial
    Time-dependent strains, when restrained, can lead to important tensile forces and damage, affecting, among other aspects, the shear response and ultimate load carrying capacity of shear-critical RC frames. This paper ...
  • 3D FEM model development from 3D optical measurement technique applied to corroded steel bars 

    Fernández Pérez, Ignasi; Bairán García, Jesús Miguel; Marí Bernat, Antonio Ricardo (2016-10-15)
    Article
    Accés restringit per política de l'editorial
    Understanding the mechanical effects of the corrosion pits on the steel surface requires an accurate definition of their geometry and distribution along the rebar. 3D optical measurement technique is used to obtain the ...
  • Full slenderness range DSM approach for stainless steel hollow cross-sections 

    Arrayago Luquin, Itsaso; Rasmussen, Kim J.R.; Real Saladrigas, Esther (2017-06)
    Article
    Accés restringit per política de l'editorial
    This paper studies the cross-sectional behaviour of austenitic, ferritic and duplex stainless steel hollow sections subjected to several loading conditions and presents a full slenderness range DSM approach for the prediction ...
  • Finite element modelling of internal and multiple localized cracks 

    Saloustros, Savvas; Pelà, Luca; Cervera Ruiz, Miguel; Roca Fabregat, Pedro (2017-02)
    Article
    Accés restringit per política de l'editorial
    Tracking algorithms constitute an efficient numerical technique for modelling fracture in quasi-brittle materials. They succeed in representing localized cracks in the numerical model without mesh-induced directional bias. ...
  • Experimental evaluation of the shear strength of aerial lime mortar brickwork by standard tests on triplets and non-standard tests on core samples 

    Pelà, Luca; Kasioumi, Konstantina; Roca Fabregat, Pedro (2017-04)
    Article
    Accés restringit per política de l'editorial
    This paper presents the results of an experimental program carried out in the laboratory to evaluate the shear strength of aerial lime mortar brickwork. Masonry triplets and walls were tested after one year from their ...
  • Seismic safety assessment of historical structures using updated numerical models: the case of Mallorca cathedral in Spain 

    Elyamani, Ahmed; Roca Fabregat, Pedro; Caselles Magallón, Josep Oriol; Clapes Boixader, Jaime (Elsevier, 2017-04)
    Article
    Accés restringit per política de l'editorial
    The paper presents an integrated approach aimed at assessing the seismic safety of Mallorca cathedral. This cathedral is an extraordinary historical construction dating back to the middle-ages. The experimental modal ...
  • Finite elements vs. equivalent-frame models for URM walls’ in-plane behaviour 

    Siano, Rossella; Camata, Guido; Sepe, Vincenzo; Spacone, Enrico; Roca Fabregat, Pedro; Pelà, Luca (2017)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    As a consequence of the large number of masonry buildings and their important historical value, there is an ongoing effort to investigate their structural behaviour. This has led to a continuous development of new methodologies ...
  • New models for structural analysis of composite beams 

    Turmo Coderque, José; Lozano Galant, Jose Antono; Mirambell Arrizabalaga, Enrique; Xu, Dong (2016)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Most codes assume a rigid interaction between concrete and steel in composite beams. This assumption assumes that there is no relative slip at the interface of both materials and Navier’s hypothesis is fully applicable. ...
  • Structural behaviour of prestressed concrete sleepers produced with high performance recycled aggregate concrete 

    Gonzàlez Corominas, Andreu; Etxeberria Larrañaga, Miren; Fernández Pérez, Ignasi (2017-02)
    Article
    Accés restringit per política de l'editorial
    A comparative analysis of the structural behaviour of prestressed concrete sleepers made with high performance concrete (HPC) and high performance recycled aggregate concrete (HPRAC) is presented in this study. Two types ...
  • Material characterization and micro-modeling of a historic brick masonry pillar 

    Drougkas, Anastasios; Roca Fabregat, Pedro; Molins i Borrell, Climent (Taylor & Francis, 2016-10)
    Article
    Accés restringit per política de l'editorial
    A masonry pillar composed of solid clay bricks, cement mortar and infill is extracted from a historical structure and tested in concentric compression. It is subjected to cyclic and monotonic loads up to compressive ...
