摘　　要：研究木结构古建筑的抗震性能对保护和开发我国古建筑遗产具有重要意义。本文以抬梁式殿堂型木结构建筑为例,结合试验结果,对其独特的结构形式、工作机制和抗震性能进行了研究,结果表明特殊的台基构造方式,柱根浮搁于础石及榫卯斗的半刚性连接使得木结构古建筑具有较好的抗震消能特性。It is imperative to preserve Chinese historical timber buildings （CHTB） because the impact of time and environment has seriously reduced the resistance capability of these historical relics. As the most complicated structure, the highest grade and the most typical representation of CHTB, the palace structure was selected as a research object. The unique structural form and characteristics, loadtransferring mechanism and seismic characteristics were studied combined with the test results. It is shown that CHTB exhibit good behaviors of energy dissipation and vibration reduction. The main and important reasons are the unique structural style, the construction of raised platform, without any connection between columns and plinths, and the special semi-rigid mortise-tenon joints and bracket set connections.
