Thesis Abstract

The abstract for the thesis "Structural Health Monitoring of Bridges Using Wireless Sensor Networks" is as follows Bridges play a critical role in the transportation infrastructure, providing safe passage for vehicles and pedestrians. However, the deterioration of bridges over time due to various factors such as environmental conditions, aging, and traffic loads poses a significant challenge to their structural health and safety. Structural health monitoring (SHM) has emerged as a vital tool for assessing the condition of bridges and ensuring their safety and longevity. This thesis focuses on the application of wireless sensor networks (WSNs) for structural health monitoring of bridges. WSNs offer a cost-effective and efficient solution for real-time monitoring of structural behavior, enabling early detection of structural abnormalities and potential risks. The integration of WSNs with advanced data processing and analysis techniques provides valuable insights into the structural performance of bridges and facilitates informed decision-making for maintenance and repair activities. Chapter 1 provides an introduction to the research topic, background information on structural health monitoring, problem statement, objectives, limitations, scope, significance of the study, structure of the thesis, and definitions of key terms. Chapter 2 presents a comprehensive literature review covering ten key aspects related to structural health monitoring, wireless sensor networks, bridge monitoring technologies, and relevant case studies. Chapter 3 outlines the research methodology, including the selection of sensor types, deployment strategies, data acquisition methods, data processing techniques, and validation procedures. The chapter also discusses the calibration and maintenance of sensors, as well as the integration of WSNs with structural analysis tools for performance evaluation. In Chapter 4, the findings of the structural health monitoring of bridges using wireless sensor networks are presented and discussed in detail. The chapter includes the analysis of sensor data, detection of structural anomalies, evaluation of bridge performance indicators, and comparison with established standards and guidelines. Chapter 5 concludes the thesis by summarizing the key findings, discussing the implications of the research, highlighting the contributions to the field of structural health monitoring, and providing recommendations for future research directions. The thesis underscores the importance of leveraging wireless sensor networks for effective and reliable structural health monitoring of bridges to ensure their safety, resilience, and sustainability in the face of evolving challenges and demands.
