    • Adaptive and off-line techniques for non-linear multiscale analysis 

      Zaghi, Stefano; Martínez García, Javier; Rossi, Riccardo; Petracca, Massimo (2018-08-22)
      Article
      Open Access
      This paper presents two procedures, based on the numerical multiscale theory, developed to predict the mechanical non-linear response of composite materials under monotonically increasing loads. Such procedures are designed ...
    • Advanced tools for fast micro-modelling of masonry structures 

      Petracca, Massimo; Marano, Corrado; Camata, Guido; Pelà, Luca (International Centre for Numerical Methods in Engineering (CIMNE), 2021)
      Conference report
      Open Access
      Among all the approaches commonly used to study masonry structures, micro-modelling is the most accurate. Masonry can be seen as a composite material made of bricks and mortar joints. Their different mechanical properties, ...
    • Computational multiscale analysis of masonry structures 

      Petracca, Massimo (Universitat Politècnica de Catalunya, 2016-04-13)
      Doctoral thesis
      Open Access
      Covenantee:   Università degli Studi G.D'Annunzio
      Masonry is an ancient building material that has been used throughout the history, and it is still used nowadays. Masonry constitutes the main building technique adopted in historical constructions, and a deep understanding ...
    • Micro-scale continuous and discrete numerical models for nonlinear analysis of masonry shear walls 

      Petracca, Massimo; Pelà, Luca; Rossi, Riccardo; Zaghi, Stefano; Camata, Guido; Spacone, Enrico (2017-09)
      Article
      Open Access
      A novel damage mechanics-based continuous micro-model for the analysis of masonry-walls is presented and compared with other two well-known discrete micro-models. The discrete micro-models discretize masonry micro-structure ...
    • Multiscale computational first order homogenization of thick shells for the analysis of out-of-plane loaded masonry walls 

      Petracca, Massimo; Pelà, Luca; Rossi, Riccardo; Oller Martínez, Sergio Horacio; Camata, Guido; Spacone, Enrico (2017-03)
      Article
      Open Access
      This work presents a multiscale method based on computational homogenization for the analysis of general heterogeneous thick shell structures, with special focus on periodic brick-masonry walls. The proposed method is ...
    • Numerical investigation of non-linear equivalent-frame models for regular masonry walls 

      Siano, Rossella; Roca Fabregat, Pedro; Camata, Guido; Pelà, Luca; Sepe, Vincenzo; Spacone, Enrico; Petracca, Massimo (2018-10)
      Article
      Open Access
      The accuracy of the Equivalent Frame Method (EFM) in modelling the seismic non-linear behaviour of unreinforced masonry (URM) buildings is investigated for regular walls (i.e. walls with regular openings’ distribution) ...
    • Regularization of first order computational homogenization for multiscale analysis of masonry structures 

      Petracca, Massimo; Pelà, Luca; Rossi, Riccardo; Oller Martínez, Sergio Horacio; Camata, Guido; Spacone, Enrico (2016-02)
      Article
      Open Access
      This paper investigates the possibility of using classical first order computational homogenization together with a simple regularization procedure based on the fracture energy of the micro-scale-constituents. A generalized ...
    • Validation of non-linear equivalent-frame models for irregular masonry walls 

      Camata, Guido; Marano, Corrado; Sepe, Vincenzo; Spacone, Enrico; Siano, Rossella; Petracca, Massimo; Roca Fabregat, Pedro; Pelà, Luca (Elsevier, 2022-02)
      Article
      Restricted access - publisher's policy
      This article compares the results obtained from the analyses of seven two-story masonry walls with an asymmetric arrangement of the openings. The walls are modelled with finite elements detailed micromodels and equivalent ...
