This study investigates the wind-resistant performance of a masonry pagoda using ABAQUS. Modal analysis was first conducted to identify the first six vibration modes. Wind speed time histories generated via the harmonic superposition method in MATLAB were converted into wind pressure and applied to the pagoda’s surface. The time-history analysis method was employed to study wind-induced vibrations, obtaining nodal displacement time-history responses. Comparative analyses of structural responses were performed under 0° and 90° wind directions. Finally, Carbon fiber reinforced plastic (CFRP) reinforcement was applied, with post-reinforcement damage analysis systematically compared to the pre-reinforcement damaged state. The results demonstrate that the door openings and damaged areas of the pagoda exhibit heightened wind sensitivity. The structural displacement response primarily occurs along the Z-axis, with magnitudes increasing proportionally to elevation. The 90° wind direction is identified as the most critical, inducing maximum dynamic responses. CFRP reinforcement effectively reduces displacement and stress values while significantly improving structural stability.
