Reinforcement Of Historical Arch Structures with CFRP Fabric Using Finite Element Method

Stone arches have been among the important structures in architecture and engineering throughout history. However, they can be damaged over time due to environmental impacts, conditions of use and natural disasters. Therefore, modern strengthening methods are needed to increase their durability. Carbon Fiber Reinforced Polymer (CFRP) fabric offers an effective solution for strengthening stone arches due to its high strength, light weight and corrosion resistance. In this study, CFRP applications were performed on a stone arch model with a length of 478 cm, a width of 40 cm and a span of 420 cm. Four different models without CFRP, 15 cm single strip, 10 cm double strip and 5 cm triple strip CFRP were created in the analysis using ANSYS program. Roman mortar was used between the stones and 0.1 mm epoxy was used as CFRP adhesive. Within the Finite Element Model (FEM), the application steps of 0.2 mm thick CFRP fabrics are described in detail. The results show a significant increase in the durability of stone arches reinforced with CFRP and that there are key points to be considered in the application.
