      López López, David; Roca Fabregat, Pedro; Liew, Andrew; Méndez Echenagucia, Tomás; Van Mele, Tom; Block, Philippe (Elsevier, 2022-01)
      Article
      Accés obert
      The Extended Limit Analysis of Reinforced Masonry (ELARM) is a simple and user-friendly method for the design and structural analysis of singly-curved, reinforced tile vaults (López López et al., 2019). It is based on limit ...
    • Analytical models to determine in-plane damage initiation and force capacity of masonry walls with openings

      Article
      Accés obert
      Masonry panels consisting of piers and spandrels in buildings are vulnerable to in-plane actions caused by seismicity and soil subsidence. Tectonic seismicity is a safety hazard for masonry structures, whereas low-magnitude ...

      Text en actes de congrés
      Accés obert
      In the present paper we compute upper and lower bounds for limit analysis in two and three dimensions. From the solution of the discretised upper and lower bound problems, and from the optimum displacement rate and stress ...
    • Comparison of seismic analysis methods applied to a historical church struck by 2009 L’Aquila earthquake 

      Endo, Yohei; Pelà, Luca; Roca Fabregat, Pedro; da Porto, F.; Modena, C. (2015-07)
      Article
      Accés obert
      This paper presents the seismic assessment of a historical church by means of different analysis methods. The church of San Marco, seriously damaged by 2009 L’Aquila earthquake, Italy, is chosen as case-study. The analysis ...
    • Computational limit analysis for anchors and retaining walls 

      Muñoz Romero, José; Lyamin, Andrei V.; Huerta, Antonio (Universitat Politècnica de Catalunya. Escola Tècnica Superior de Camins Canals i Ports de Barcelona, 2011-11-15)
      Comunicació de congrés
      Accés obert
      The computation of the bearing capacity of engineering structures commonly relays on results obtained for simple academic examples. Recent developments in computational limit analysis have allowed engineers to compute ...
    • Decomposition techniques in computational limit analysis 

      Muñoz Romero, José; Rabiei, Syednima; Huerta, Antonio (2013)
      Comunicació de congrés
      Accés obert
      Numerical techniques for the computation of strict bounds in limit analyses have been developed for more than thirty years. The efficiency of these techniques have been substantially improved in the last ten years, and ...
    • Lower bound element and submodel for modelling of joints between precast concrete panels 

      Herfelt, Morten A.; Poulsen, Peter N.; Hoang, Linh C.; Jensen, Jesper F. (CIMNE, 2015)
      Comunicació de congrés
      Accés obert
      In practice, precast concrete structures are designed using either analytical methods or linear finite element tools, and the in-situ cast joints between the precast panels are assessed using conservative empirical design ...
    • Multi-level numerical modelling and analysis of tile vaults 

      López López, David; Mendes, Nuno; Oliveira, Daniel V.; Calderón Valdiviezo, Lucrecia Janneth; Domènech Rodríguez, Marta (Multidisciplinary Digital Publishing Institute (MDPI), 2023-08-11)
      Article
      Accés obert
      The complex structural behaviour of masonry, with its brittle response in tension, frictional response in shear, and anisotropy, makes it challenging to model accurately. Tile vaults, with their unique features such as ...
    • Optimal collapse simulator for three-dimensional frames 

      Sarrate Ramos, Josep; Huerta, Antonio; Bonet Carbonell, Javier; Peraire Guitart, Jaume; Saà Seoane, Joel; Vidal Codina, Ferran (Universitat Politècnica de Catalunya. Escola Superior d'Enginyers de Camins Canals i Ports de Barcelona, 2011-11-15)
      Comunicació de congrés
      Accés obert
      In this work a limit analysis for 3D structures software package is presented. The goal is to obtain for a certain structure the load factor λ that applied to the external loads induces collapse to the structure. The ...
