Engineered cementitious composite (ECC), a new type of building material possessing high strength and excellent ductility, presents wide application prospects in strengthening engineering. This thesis takes advantage of these characteristics of ECC to put forward a protection scheme using ECC surfaces to reinforce the Small Wild Goose Pagod and improves its seismic performance of ancient pagoda. Using the finite element software ANSYS, the full size of the Small Wild Goose Pagoda is modeled via a monolithic masonry model. According to the national standard Code for Design of Masonry Structures and referencing the actual condition of the pagoda, the degree of damage to its bricks, and the multi-linear kinematic hardening model, the uniaxial stress-strain curve of the masonry is adjusted. The damage criterion of materials is further defined using five Willam-Warnke parameters. The El Centro seismic wave is selected as the ground motion input, and three levels of amplitude modulation are adopted. The maximum acceleration values of the three conditions are 70, 220, and 400 gal. The seismic response of the model was analyzed using dynamic time-history analysis methods, and the maximum displacement and acceleration of each layer are extracted. The story drift is also calculated. The criteria show that the pagoda is seriously damaged to the brink of collapse when the peak earthquake acceleration is 400 gal. The earthquake response of the pagoda notably decreased after establishment of the ECC reinforcement model of the Small Wild Goose Pagoda. The analysis results demonstrated that the ECC surface layer reinforcement can significantly enhance the overall ductility and bearing capacity of the tower, effectively improving its damage tolerance. This work provides a reference for the practical application of ECC in ancient tower seismic reinforcement for earthquake protection.
