西北干旱地区传统建筑安全性能研究——以永登县红城感恩寺碑亭为例

Study on Safety Performance of Traditional Architecture in Arid Area of Northwest China:Taking Yongdeng Hongcheng Gratitude Temple Pavilion as an Example

西北地区传统建筑易于受到恶劣干旱环境的侵蚀和破坏,迫切需要评判其重要构件与节点的安全性能,做到科学延续传统建筑的生命周期。以永登红城感恩寺碑亭为例,建立主要承重结构有限元分析模型,依据构件、构架的残损检测数据,修正分析模型,开展具体构件、连接节点承载力及其结构整体的静力学研究,以期结合本地区的环境条件,讨论传统建筑的安全性能及其破坏发展趋势。

The traditional architecture in Northwest China is easy to be eroded and destroyed by the harsh arid environment.Therefore,it is urgent to judge the safety performance of its important components and nodes,so as to extend the life cycle of traditional architecture scientifically.Taking Yongdeng Hongcheng Gratitude Temple Pavilion as an Example,the finite element analysis model of the main load-bearing structure was established,according to the damage detection data of component and frame,the analysis model was revised,statics research on specific components,joint bearing capacity and its structure as a whole was carried out,and combining the environmental conditions of the region,the safety performance and destruction developing trends of traditional buildings was discussed.
