Seismic response of masonry pagodas considering soil-structure-interaction (SSI) effect and CFRP reinforcement

This study examines the seismic reinforcement of pagodas, a component of historical heritage, by initially evaluating the impact of soil-structure interaction (SSI) on the seismic response of pagodas, which was determined to substantially elevate the danger of damage to these structures. The study suggests a way to enhance the seismic performance of the pagoda by reinforcing it with carbon fiber-reinforced polymer (CFRP) composites. The lightweight, high-strength, and corrosion-resistant characteristics of CFRP render it a suitable material for reinforcing the pagoda. The primary tensile stress analysis revealed the pagoda's vulnerabilities, leading to the strategic application of CFRP reinforcement. The strengthening methods substantially enhanced the seismic performance of the pagoda, mitigated the brittle damage traits of the masonry structure, diminished the extent of tensile damage, and extended the damage time frame of the building. The study's results validate that the CFRP strengthening technique offers an effective novel solution for the seismic reinforcement of masonry structures, with potential for widespread adoption and application.
