Abstract As invaluable historical legacies, the preservation of ancient pagodas is of paramount importance, not only because they embody rich cultural significance but also due to their vulnerability in the face of natural disasters. Seismic reinforcement has become one of the key measures for the conservation of ancient pagodas. This study initially focuses on the Soil-Structure Interaction (SSI) effect, an often-neglected factor that is crucial to the seismic response of ancient pagodas. Through in-depth analysis, it has been discovered that the SSI effect significantly increases the risk of damage to ancient pagodas. To enhance the seismic performance of ancient pagodas, this research proposes a strategy for reinforcement using high-performance Carbon Fiber-Reinforced Polymer (CFRP) composite materials. Known for its lightweight, high-strength, and corrosion-resistant properties, CFRP offers an innovative solution for the structural reinforcement of ancient pagodas. By conducting a principal tensile stress analysis of the pagodas, the weak links have been identified, and targeted CFRP reinforcement has been implemented. The reinforced pagodas have shown a significant improvement in seismic performance, not only ameliorating the brittle failure characteristics of masonry structures but also effectively reducing the extent of tensile damage and prolonging the structural damage timeline. These findings indicate that CFRP reinforcement provides an effective new approach for the seismic reinforcement of masonry structures, with broad prospects for promotion and application.
