“…A basis of our numerical model is finite-discrete element method which offered the framework for simulation of the main discontinuity effects in the dry-stone masonry structures such us sliding of the stone blocks and their fracture and fragmentation 2, 3. Few years ago our team developed 2D numerical model for dry-stone masonry structures with embedded dowels and clamps [4]. The model is based on finite-discrete element method and can simulate movement of the stone blocks, their fracture and fragmentation, yielding and extracting of the clamps and dowels and failure of the structure.…”

In this work, numerical investigations of the behaviour of dry stone masonry structures, reinforced with metal connectors (clamps and dowels), were performed by the finite-discrete element model for strengthened dry-stone masonry structures. The geometrical and material model of the metal connectors were developed and implemented into the finite-discrete element model in order to analyse the influence of the connectors to strengthening capacity of the structure. The yielding and extracting of the connectors (clamps and dowels) from the holes were represented by experimental force-displacement curves, obtained by testing the samples composed of two stone blocks connected with clamps or dowels. An incremental dynamic analysis up to the structural failure was applied in order to determine failure mechanisms and collapse load. The results were compared to those obtained for unreinforced structures. The results show the performance of the applied model in simulation of the behaviour of historical monuments, composed of stone blocks with dry joints and connectors, in the dynamic regime. The model is complex and time consuming, but it can be useful for making decisions related to reconstruction and increasing the earthquake resistance of the historical buildings.

“…A commonly used method for connecting the stone blocks in the past was the embedding of the metal clamps and dowels into the pre‐made holes that were subsequently backfilled with infill material, such as lead. Clamps are used for the strengthening of dry‐stone walls and arches in order to increase their tension bearing capacity (Figures a, b), while the dowels connect the capitals and columns or capitals and upper beams, and dominantly increase shear bearing capacity (Figure c) . The first found examples of iron clamps dated from the 6th century BC in the Ancient Greece.…”

“…Key idea, which led to this experiment, was how the strengthening with clamps and dowels influence to the seismic resistance of these structures. Few years ago our team developed 2D numerical model for dry‐stone masonry structures with embedded dowels and clamps. The model is based on finite‐discrete element method and can simulate movement of the stone blocks, their fracture and fragmentation, yielding and extracting of the clamps and dowels and final failure of the structure.…”

Throughout history, dry-stone masonry structures have been strengthened with different types of metal connectors in order to increase their resistance which enabled their survival, especially in the seismically active area. One such example is the ancient Protiron monument placed in the Peristyle square of the Diocletian's Palace in Split, Croatia. The Protiron was built at the turn of the 3rd century as a stone masonry structure with dowels embedded between its base, columns, capitals and broad gable. The stone blocks in the broad gable were connected by metal clamps during restoration at the beginning of the 20th century. In order to study the seismic performance of the strengthened stone masonry structures, an experimental investigation of seismic behaviour of a physical model of the Protiron was performed on the shaking table. The model was designed as a true replica model in a length scale of 1:4 and exposed to representative earthquake with increasing intensities up to collapse. The tests provided a clear insight into system behaviour, damage mechanism and failure under intensive seismic load, especially into the efficiency of connecting elements, which had a special role in increasing seismic resistance and protection of the structure from collapse. Additionally, this experiment provided valuable data for verification and calibration of numerical models for strengthened stone masonry structures.
