Abstract
In recent years, immense development in Structural Health Monitoring (SHM) of bridges helps address the life span and reliability of bridge structure at contrasting phases of their service life. This article provides a detailed understanding of bridge monitoring, and it focuses on sensors utilized and all kinds of damage detection (strain, displacement, acceleration, and temperature) according to bridge nature (scour, suspender failure, disconnection of bolt and cables, etc.) and environmental degradation under static and dynamic loading. This paper presents information about various methods, approaches, case studies, advanced technologies, real-time experiments, stimulated models, data acquisition, and predictive analysis. Future scope and research also discussed the implementation of SHM in bridges. The main aim of this research is to assist researchers in better understanding the monitoring mechanism in bridges.
Highlights
Civil engineering structures include buildings, bridges, and dams that are beginning to fail from original quality once constructed, and the usage of buildings and infrastructures is unavoidable to the whole world. erefore, it is necessary to know about the functioning of structures in terms of their life span and usage level
E sensor receives information from the structure that will be monitored for health. e sensor will be selected based on the database’s requirements. e information will instead be conditioned by amplification and filtering. e analog signal data will be transformed into digital form for computational processing in the stage of data acquisition (DAQ). e processed data is saved or sent to the appropriate access point
Lee et al studied different approaches for damage detection called continuous relative wavelet entropy- (CRWE-) based DSI. e experiment has been conducted in truss bridge structure, and the approach is found as effective to identify the levels of damage [73]
Summary
Civil engineering structures include buildings, bridges, and dams that are beginning to fail from original quality once constructed, and the usage of buildings and infrastructures is unavoidable to the whole world. erefore, it is necessary to know about the functioning of structures in terms of their life span and usage level. Erefore, it is necessary to know about the functioning of structures in terms of their life span and usage level. Excess dynamic forces such as earthquakes, heavy wind, environmental changes, and heavy goods-vehicle must track the structural integrity and detect the damage and frequently referred to as structural health monitoring [1]. Bridge structures consist of wired and wireless sensor networks, which help monitor the structure and provide data accurately. Is article outlines the proposed policy and plan in SHM of bridge structure and provides valid information about current techniques and technologies in bridge. Monitoring of bridge structure has some operational strategies, including selecting sensors, deploying, tools and automated technology, storage, and transmission. E sensor receives information from the structure that will be monitored for health. e sensor will be selected based on the database’s requirements. e information will instead be conditioned by amplification and filtering. e analog signal data will be transformed into digital form for computational processing in the stage of data acquisition (DAQ). e processed data is saved or sent to the appropriate access point
