摘　　要：为更好地保护太和殿,建立基于典型构造的太和殿有限元模型,开展模态分析、谱分析和时程分析,评价太和殿的抗震性能,结果表明,太和殿的结构主振型以平动为主;8度常遇地震作用下,太和殿的变形和内力很小;8度罕遇地震作用下,太和殿可满足抗倒塌要求。太和殿的典型构造有利于结构整体抗震。To realize better protection, a typical structure-based finite element model was created for Taihe Palace, to carry out modal analysis, spectral analysis and time history analysis, and to evaluate the seismic performance of Taihe Palace. It was found that main earthquake type of Taihe Palace structure is translation, deformation and internal force are very small under 8-degree common earthquake and Taihe Palace could satisfy the anti-collapse requirement under 8-degree rare earthquake. The typical structure of Taihe Palace is advantageous to the overall structural seismic resistance.
