结构健康监测对于历史建筑的预防性保护具有重要意义。结构响应的实时监测和预警具有及时性和早期发现结构异常状况的优点。以我国木结构古建筑飞云木阁为研究对象，对实时监测结构反应的预警机制进行了研究。提出了不同数据积累时间下的木结构历史建筑预警机制。通过对累积监测数据的统计分析和极值分析，提出了结构响应的预警阈值。采用基于功效系数法的数据融合方法，实现了建筑物下部结构的预警。真实的监测数据验证了该机制的有效性。提出的预警机制提供了一种安全健康管理的预警解决方案，可供现有建筑和其他历史建筑参考。
Structural Health Monitoring (SHM) is of great importance for the preventive protection of historical buildings. Real-time monitoring and early warning of the structural response have advantages of timeliness and early detection of abnormal structural conditions. Feiyun Wood Pavilion, a historical timber building in China, was taken as the object to study the early warning mechanism for real-time monitored structural responses. An early warning mechanism for historical timber building has been presented under different data accumulated time. The early warning thresholds of structural responses based on statistical and extreme value analysis of the accumulated monitoring data are proposed. Early warning for substructure of the building is realized by data fusion based on the efficiency coefficient method. The effectiveness of the proposed mechanism was verified by real monitoring data. The proposed mechanism gives an early warning solution of the SHM that can be references for existing and other historical buildings.
