STRUCTURAL HEALTH MONITORING OF AN OLD RC BRIDGE

Abstract: Bridges are pervasive in all communities and shape the interpersonal, sociological, environmental, financial, ethnographic, and artistic features of these organizations. SHM is required because the properties of both concrete and steel are highly dependent on a variety of factors that are difficult to foretell in practice. The typical criteria selected for monitoring a structure's health may be mechanical, physical, or chemical. Monitoring the condition and functionality of bridges on a regular basis is vital for their appropriate management and functionality. SHM systems have evolved to continually evaluate and assess the functioning state of bridges, hence enhancing maintenance, inspection, and planning. In the previous ten years, researchers have made significant advancements in all facets of SHM, such as highly developed smart sensors, wireless sensors, sensor networks, data acquisition technologies, data communication systems, signal processing systems, data management systems and system integrated techniques, approaches for damage identification, model upgrading, and safety assessment, development and implementation of SHM frameworks for practical civil infrastructure and data interpretation and application. This work aims to compile global case studies on monitoring the structural health of multiple bridges using a variety of approaches, efficiency evaluation, and instantaneous alert systems. The purpose of this study is to review Structural Health Monitoring of a bridge by carrying out non destructive test named rebound hammer along the bridge by concerned authority to obtain the reduced compressive strength parameter of superstructure of bridge and modeling and analyzing it by FEM software specifically STAAD Pro and comparing the results such as bending moments, forces, and deflections and stresses and providing required repair and rehabilitation techniques.
