This paper takes Guangyue Tower as the research object and uses ANSYS software to establish three finite element models of its upper timber structure, timber structure and high platform foundation and wooden structure, high platform foundation and soil mass. Through modal analysis, it is concluded that when the soil-structure interaction is considered, the natural frequency of the structure is reduced, and its influence on the high-order natural frequency of the structure is greater than the influence on the low-order natural frequency. Select El-Centro wave, Taft wave and artificial wave to analyze the dynamic performance. The results show that only considering the wood structure or wood structure and the high platform will make the calculated displacement smaller, so the influence of the existence of the foundation soil on the superstructure should be considered.
