DAMAGE IDENTIFICATION OF HETEROGENEOUS MATERIALS BASED ON VIBRATION AND INFORMATION FUSION

摘要：

This study aims to mix vibration testing with information fusion to improve the validity of damage detection for concrete,which is a typical heterogeneous material.Through a simulation of a concrete bridge,it is obviously indicated that the mixed method based on vibration and information fusion has nice sensitivity to concrete initial damages.Compared with the modal strain energy method,this concrete damage identification method needs much less modal information.In a word,this nondestructive testing method based on vibration and information fusion has good effects of concrete damage identification and good practicability to actual structures.
