    • A mixed algorithm for incremental elastoplastic analysis 

      Bilotta, A.; Leonetti, L.; Garcea, G. (CIMNE, 2011)
      Conference report
      Open Access
      A new method for the incremental analysis of elastoplastic associated materials is presented. The method fully retains all the equations and variables of the problems at the same level and uses a sequential quadratic ...

    • A quasi-static nonlinear analysis for assessing the fire resistance of 3d frames exploiting time-dependent yield surface 

      Magisano, D.; Liguori, F.; Leonetti, L.; de Gregorio, D.; Zuccaro, G.; Garcea, G. (CIMNE, 2019)
      Conference report
      Open Access
      In this work an automatic procedure for evaluating the axial force-biaxial bending yield surface of reinforced concrete sections in fire is proposed. It provides an accurate time-dependent expression of the yield condition ...

    • An efficient numerical method for shakedown analysis 

      Bilotta, A.; Leonetti, L.; Garcea, G. (CIMNE, 2013)
      Conference report
      Open Access
      The algorithm proposed in [9] for incremental elastoplasticity is extended and applied to shakedown analysis. Using the three field mixed finite element proposed in [22] a series of mathematical programming problems or ...
