Based on fuzzy mathematics method, earthquake damage prediction of stone structure houses in Southern Fujian is studied. The subsets of earthquake damage affecting factors applicable to stone structures and their fuzzy relation with earthquake damage levels are established. Furthermore, the earthquake damage prediction model of stone structure houses in southern Fujian is developed based on fuzzy comprehensive evaluation method. Taking the two-storey stone structure house as an example, the model is applied to predict and evaluate the damage state of the two-storey stone structure house after earthquake damage. The results show that, according to the fuzzy comprehensive prediction and evaluation model, the stone structure house suffers serious damage degree in the earthquake damage, the evaluation grade of earthquake damage is C, and the evaluation result is consistent with the actual damage state. The model of earthquake damage prediction is clear and easy to calculate, which provides a theoretical basis for earthquake damage prediction and reinforcement and maintenance of stone structure houses in southern Fujian.
