Numerical Simulation Analysis of Chinese Timber Frame Ancient Buildings - An Example of the Hall of Supreme Harmony in the Forbidden City

Abstract

Chinese ancient architecture is renowned for its unique large wooden structures and standards. However, the safety of the wooden structures in the Forbidden City has gradually deteriorated over long-term use. At present, most building safety evaluation methods rely on qualitative assessments rather than quantitative identifications. In the process of conducting safety evaluations, it is necessary to conduct sufficient analysis and judgment of building damage to determine the safety status of ancient buildings. To ensure the safety of the buildings, this study takes the Hall of Supreme Harmony in the Forbidden City as an example, using numerical simulation methods to analyze the components of Chinese wooden ancient architecture through finite element analysis, with the aim of quantitatively protecting China's traditional architectural cultural heritage. This study provides a scientific basis for the protection of China's traditional architectural cultural heritage and has high practical significance. The results showed that the deformation peak and internal force were within the allowable range according to relevant specifications.
