The increasing importance of considering structural scale effects demands better understanding of such effects and their influence on structural properties. To this end, two models of the full-scale Xiaowan Arch Dam, at 1/1500-scale and 1/3000-scale units respectively, are elaborated to numerically and experimentally investigate scale effects on structural dynamic properties and responses. From the experimental aspect, experimental modal analysis shows that the natural frequency of the small arch dam model is greater than that of the large arch dam model, and the two models have similar mode shapes. Five different levels of excitation are used to clarify the random response characteristics of the models, with similar maximal velocity responses in the vertical and horizontal directions observed in all cases. From the numerical aspect, the finite element method is used to analyze the structural dynamic properties and responses of the corresponding simulated arch dam models. The numerical maximum velocity responses have the same orderliness as those from the experiments, indicating the effectiveness of numerical simulation in analyzing size effects on structural dynamic properties and responses.
