Numerical Analysis of Confined Masonry Structures by Finite Discrete Element Method

This paper presents numerical model for confined masonry structures under seismic load based on combination of the finite discrete element models for reinforced concrete confining elements and 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 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 shown on the example of confined masonry wall exposed to seismic excitation.
