基于振动监测的桥梁结构损伤识别方法研究

The research of bridge structural damage recognition method based on vibration monitoring

桥梁结构损伤识别是桥梁结构安全监测系统的核心,结构振动模态的变化能够直接反应桥梁结构损伤的程度,分析提出基于结构振动模态变化率作为桥梁结构损伤识别指标,从而识别结构的损伤程度以及损伤位置。

Structural damage identification bridge is the core of the bridge structure safety monitoring system.Changes in the structure of the strain can bring a direct response to the extent of damage to the bridge structure.The analysis presented in this paper based on the strain rate changes in the structure as a bridge structure damage identification index,which damage the structure of the process to identify and damage location
