The traditional architecture of the Dong and other ethnic minorities show cases unique architectural skills. Its conservation is significant for maintaining the diversity of national culture and transmitting traditional craftsmanship. This study used ABAQUS software to analyse the mechanical properties of two typical wind and rain bridge structures. The results show that the arch bridge structure of Model 2 is significantly better than the simply supported beam bridge structure of Model 1 in terms of load-bearing capacity. Specifically, the mid-span deflection of Model 2 is only approximately 7% of that of Model 1. In addition, the El-Centro seismic wave was selected as the excitation data for this study, and the time-history analysis was performed according to the 7-degree seismic fortification standard. The results demonstrate that the arch bridge structure of Model 2 also performs well in terms of seismic performance, with lower acceleration responses at both mid-span analysis points compared to that of Model 1. These findings provide a scientific basis for the structural optimisation of wind and rain bridges and offer valuable insights into the modern conservation and continuation of traditional architectural heritage.
侗族和其他少数民族的传统建筑展现出独特的建筑技艺。其保护对于维护民族文化多样性和传承传统工艺具有重要意义。本研究使用ABAQUS软件分析了两种典型风雨桥结构的力学性能。结果表明，模型2的拱桥结构在承载能力方面明显优于模型1的简支梁桥结构。具体而言，模型2的跨中挠度仅约为模型1的7%。此外，本研究选取了El-Centro地震波作为激励数据，并按照7度抗震设防标准进行了时程分析。结果表明，模型2的拱桥结构在抗震性能方面也表现良好，与模型1相比，跨中两个分析点的加速度响应更低。这些研究结果为风雨桥的结构优化提供了科学依据，并为传统建筑遗产的现代保护与延续提供了宝贵的见解。
