The aim of this thesis is to propose a new efficient numerical tool, based on the
kinematic theorem of limit analysis, for the study of masonry shell and 3D
structures with or without FRP reinforcement.
The approach consists of two steps. In step I unreinforced masonry strength
domains are obtained with a FE limit analysis procedure applied to a representative
element of volume constituted by a central brick interacting with its six neighbours
by means of rigid plastic interfaces (mortar joint). In step II, the unreinforced
strength domains are implemented in a novel upper bound FE limit analysis code
for the analysis at collapse of entire masonry curved and 3D structures
