Abstract: Taihe Palace (The Hall of Complete Harmony) is the tallest and largest ancient building with a high research value. On the structural style, the whole model of Taihe Temple had been built, respectively, it had being researched for the antique structure and wood structure of the comparative. The results illustrate that, under permanent load, there is tiny displacement at the bottom and the maximum showed on the top. The displacement of wood structure is 2.6 times bigger than archaize structure. Otherwise, under the action of earthquake, wood structure suffered maximum displacement on the third floor, which reaches the three times than the archaize structure. It was influenced by the vertical load of horizontal load of the timber structure more seriously. Comparing to dead load, the displacement increase of wood structure was obviously larger than archaize structure.

Keywords: structure analysis; structure comparison; displacement calculation
