| Abstract | Masonry is the major material used to construct heritage masonry buildings many centuries ago. Heritage masonry buildings are valuable structures and in the case of the design, they are constructed based on religious and architecture art such as arches, domes, barrel vault, shrine, and spire. However, these heritage masonry structures are more likely to collapse in the event of natural disaster such as earthquakes, tsunamis and storm surges, floods, cyclones, and landslides because of construction age and mechanical properties.Retrofitting of heritage masonry structures is a challenging and time-consuming task in many developing nations especially in Bang, Myanmar which is one of high seismic zone in Myanmar. After 1975 Bagan earthquake and 2016 Chauk earthquakes, a lot of heritage masonry buildings are damaged and collapsed. To retrofit those heritage masonry structures, government and other organizations spend a lot of money such as retrofitting requirements, labors and consuming the time to strength the structures. In the case of retrofitting method, many retrofitting methods have been already developed in years ago. However, these traditional methods have some limitations like the high cost of retrofitting materials, require skill labors, using huge machines, time consuming.In order to address these problems, an innovative retrofit method was presented, fiber reinforced paint which is not only a simple retrofitting but also low-cost and effectiveness retrofitting method. Moreover, previous research has demonstrated that retrofitting the regular masonry houses with fiber reinforced paint with experimental evaluation under seismic loading. In the results, fiber reinforced paint can significantly improve the deformability and effective energy dissipation capacity. However, fiber reinforced paint retrofitting methods have not been developed for heritage masonry structure. In this study, experimental evaluation using shaking table have been conducted to explore the advantages of fiber-reinforced paint on heritage masonry structures. In experiment, there are two 1:4 scale model: 1) unreinforced masonry model (URM), and 2) fiber reinforced retrofitted model (FRRM), which is constructed by using the geometric dimensions and materials properties of structures in Bagan, Myanmar. |
