Nonlinear analysis of masonry structures reinforced with the CAM system

This work focuses on the numerical analysis of masonry elements reinforced with the CAM system. An efficient macromechanical finite element modeling approach is proposed to reproduce the nonlinear response of such structures, based on a plastic-damage material model. Three main factors are investigated: setting of the steel stripes pre-tensioning values, definition of the boundary conditions, and calibration of the stripes post-yielding behavior. Hence, sensitivity analyses on pretensioning stress are carried out to investigate the effectiveness of the CAM system and provide designers with some useful recommendation.
