State-of-the-art review of bridges and bridge networks resilience using science mapping approach

In recent years, lot of attempts have been made to incorporate the resilience framework into decision-making, establish the best use of available resources, and reduce the impact of hazards on bridges and bridge networks. However, scholarly research in this area is still in its early phases, with a minimal exploration of research gaps and future prospects. Therefore, this study presents a state-of-the-art review of bridge and bridge network resilience studies using a science mapping approach. The research on the said topic was obtained from the Scopus literature database. After that, the literature database was analysed using the VOSviewer and NVIVO tools to display the domain-specific body of knowledge. Then, the study focused on the most prolific researchers and disaster types, bridge resilience assessment approaches, current research trends, future directions, and theoretical and practical implications. The bridges and bridge networks resilience research paradigm is changing toward the usage of digital tools and technologies. In this context, the study proposed a framework by integrating BIM-GIS and digital twins' models. Thus, the proposed framework can aid bridge owners in accumulating iterative data, creating multi-hazard disaster preparedness policies, designing, and enhancing life-cycle managing and maintenance tasks of bridges and bridge networks.
