Structural Damage Information Decision Based on Z-numbers

Authors: Yangxue Li; Yong Deng

Structural health monitoring (SHM) has grate economic value and research value because of the application of finite element model technology, structural damage identification theory, intelligent sensing system, signal processing technology and as so on. A typical SHM system involved three major subsystems: a sensor subsystem, a data processing subsystem and a health evaluation subsystem. It is significance of sensor data fusion for the data processing subsystem. In this paper, considering the fuzziness and reliability of the data, the method based on Z-numbers is proposed in the damage information fusion for decision level, which is a softer method and avoids the severe effect of a small data on the fusion result. The result given by the simulation example of space structure shows the effectiveness of this method.
