| 摘 要： | 为对古建筑木构架的安全性评价提供依据,通过对脱榫状态下的燕尾榫进行静力试验研究,分析得到残损状态下的木构架力学性能。按照预加载-加载的试验方案对构架进行试验。通过对试验数据的分析,得出了节点主要破坏形式、脱榫量对构架破坏的影响、极限承载力及极限荷载的取值方法并结合理论分析试验数据。

| Abstract: | In order to accurately grasp the relationship between damaged wooden frame nodes and their mechanical properties and to provide a foundation for evaluating the overall safety of a structure, a reduced scale, single room architectural model in a 1:2 ratio was built according to Qing Dynasty construction codes in magnificent building size. The dovetails of the model building were of four different degrees of off the tongue. Through vertical loading tests, the main forms of node damage and ultimate load bearing capacity were recorded and analyzed. The experimental data and conclusions can be used as reference for researchers doing similar structural analysis. |
