Abstract
Study on Modern Bridge Structure Health Monitoring System Based on Damage Identification
Highlights
With the development of the world economy and the needs of the human living environment, various large-scale civil engineering structures have emerged in large numbers
Based on the above research, this paper proposes a research method of modern concrete bridge structure health monitoring by damage identification
The bridge health monitoring system is developing in the direction of networked data transmission and storage, integrated management of monitoring projects, intelligent monitoring of monitoring instruments, and real-time interaction
Summary
With the development of the world economy and the needs of the human living environment, various large-scale civil engineering structures have emerged in large numbers. Panesso et al [4] have carried out the theoretical and experimental studies on the identification of structural damage characteristics, the status of structural work, and the location of structural damage, health monitoring sensor systems, large-scale monitoring data analysis technology, and machine vision measurement. The experimental analysis adopts the measured response of the structure to perform damage identification and state assessment under the complex load and environmental coupling. Compared with the health monitoring system using advanced sensors, the holographic deformation of the bridge structure obtained is more sensitive to local damage, and it overcomes the limitation caused by the number of sensors. In the formula above, the root mean square error (RMSE) is used to measure the deviation between the Figure 1 Flow chart of principal component analysis
