桥梁的损伤识别

现在很多桥梁都安装了监测系统 ,自动损伤识别是桥梁健康监测系统的核心技术和热点研究问题。文章介绍了几种桥梁损伤的识别方法 ,包括动态法、静态法、有模型法、无模型法、位移法、应变法以及 BP和 RBF神经网络法的比较。目前健康监测系统尚不具备损伤识别能力。如何设计一个高效的用于结构损伤识别的自动损伤识别系统 ,是个值得研究的问题

Damage detection of bridges

As many bridges have been installed with monitoring systems presently, automatic damage detection becomes a core technique of bridge health monitoring systems, which attracts the attention of many researchers. In this paper, several damage detection methods for bridges are reviewed, including the dynamic and static methods, the model and non model methods, the displacement and strain methods, and BP and RBF artificial neural network methods. The present bridge health monitoring systems have not the capacity to detect the damage in bridges.Further study is needed as to how to design an effective automatic damage detection systems for structural damage indentification.
