木结构文物建筑结构检测技术要点探讨

Discussion on structure test technical points for heritage building of timber structure

本文主要从结构体系和荷载水平、木材材质、结构整体、承重构件和构架、主要节点和连接的工作状态等方面探讨了木结构文物建筑结构检测的技术要点,并结合工程实例分别采用超声波法和应力波法对木材的内部缺陷进行了无损检测,最后提出检测结论,为类似木结构文物建筑的结构检测提供了参考。

Mainly from structure system and load level,lumber quality,the whole structure,load-bearing members and frame,work state of the main nodes and connections and so on,structure test technical points for heritage building of timber structure were discussed. Combined with the engineering example,the nondestructive testing of lumber internal defects was carried out the by means of ultrasonic method and stress wave method respectively. Finally,Test conclusion was put forward,and it offers a benchmark example for structure test of similar heritage building of timber structure.
