Research on Early Warning Mechanism of Structural Health Monitoring System on Ancient Timberwork

With unclear material parameters of old wood and structural parameters of old buildings,random distribution of structural damage,there are many difficulties in dealing with static data collected from the monitoring system.In the design of early warning mechanism,following which principles to set warning limits plays an important part in displaying the monitoring function of the system.Take Tibetan ancient buildings for example,the paper discusses the design methods of early warning mechanism of structural health monitoring on ancient timberwork and the principle of setting warning limits for monitoring system.It also gives the method of analyzing random data and judgment criterion,coping measures.Expound the above methods in detail combined with the engineering.
