Representation and measurement of the beam health based on one-dimensional model

摘要：

　　This paper proposes a method for online structural health evaluation, and analyzes the correlation between online monitoring data and structural health status.On the basis of this analysis, the structural health can be evaluated by using the deviation of the cunent status from the initially designed status.The health degree index, representation and measurement models are also defined for structural health evaluation in this work.A numerical case study is conducted to validate the related concept and health evaluation model using a beam under pressure loads.The results indicate that the proposed method can effectively represent the structural health status.
