故宫神武门防震构造研究

Study on the Antiseismic Constitution of Shen-Wu Gate in the Palace Museum

本文论述了故宫神武门防震构造,通过对台基夯实、柱脚平搁、侧脚及生起、榫卯连接、斗分层、梁架稳定、屋顶厚大、平面对称等构造进行理论分析,得出了古建筑具有良好防震性能的结论。

The antiseismic constitution of Shen-Wu gate in the Palace Museum is studied in this paper. It discusses in detail about the following： strong foundation, the column foot locates on the stone base, the incline of the column foot, the gradually increase of the height of the column from the center to the comer of the building,tension-mortise joints,layers of bracket sets, stable beams, huge roof and symmetrical layout of the building and so on. The results show that Chinese ancient buildings have the ability to resist seismic forces.
