Sažetak
A commonly used method for increasing the resistance of historical structures, made of stone blocks with dry joints, is strengthening with the metal connectors. The numerical modelling of these structures is demanded due to a discontinuous nature and composition of the materials with significantly different properties. This paper presents a finite-discrete element numerical model for analysis and prediction of the collapse of dry stone masonry structures strengthened with steel clamps and bolts. The model includes fracture and fragmentation of the blocks as well as a cyclic behaviour, yielding, stiffness degradation, failure and the influence of pulling out of the clamps and the bolts from the stone block. The developed model can capture damage mechanisms of the structure both at the joint and the block level, coupled with the deformation and extracting of the connectors from the holes. The capabilities of the presented approach are demonstrated in the seismic analysis of the strengthened dry-stone structure .The developed model can be used for the estimation of the seismic resistance of historical dry stone masonry structures reinforced with steel clamps and steel bolts, which is very important for the structures classified as cultural heritage.
