Numerical model for confined masonry structures based on finite discrete element method
This paper presents a numerical model for confined masonry structures under seismic load. The model is based on a combination of the finite discrete element models for reinforced concrete confining elements and a masonry infill. Material non- linearity, including fracture and fragmentation of discrete elements, is considered through contact elements, which are implemented within a finite element mesh. The model includes the following phenomena: non-linear cyclic behaviour of concrete, reinforcement and masonry during the seismic event, interaction between the reinforcement and concrete, cracking of the reinforced concrete confining elements and masonry units, as well as failure and softening in tension and shear for mortar joints. The application of the developed numerical model is exemplified on a confined masonry wall exposed to seismic excitation.
