Sažetak
This paper presents the performance of a combined finite-discrete element method (FEM/DEM) for the material and geometric non-linear analysis of the structural response of dry stone masonry structures under monotonic, cyclic and seismic loads. In the proposed modelling approach each stone block is modelled as a discrete element which is discretized by triangular finite elements. Material non-linearity including fracture and fragmentation of discrete elements as well as cyclic behaviour during dynamic load are considered through contact elements which are implemented within a finite element mesh. The numerical analysis based on experimental test data has been carried out to simulate the main features of dry stone structures. The performed analysis shows high accuracy of the numerical results in comparison with the experimental ones and demonstrates the potential of the FEM/DEM method for realistic modelling of the response of dry stone masonry structures.
