SRRI Methodology to Quantify the Seismic Resilience of Road Infrastructures

Davide Forcellini

Abstract: The assessment of the seismic risk connected with the functionality of infrastructure has become an important issue in civil engineering, and consists of estimating costs due to earthquakes. In this regard, bridges are the most vulnerable systems among the various components of road infrastructure and the assessment of their resilience has recently been proposed. However, the development of methodologies that can assess the resilience of the full road infrastructure still constitutes a gap in the literature. T… Show more

As vital infrastructure, the road network is essential for disaster mitigation and post disaster recovery. However, it is also vulnerable to natural disasters, impacting their ability to help increase city resilience. This study assesses the vulnerability of Padang City’s road network, especially in disaster-prone areas, to ensure continued functionality during emergencies, as the city is frequently exposed to natural hazards such as earthquakes, tsunamis, coastal erosion, and floods. This study delves into assessing the vulnerability of Padang’s road network, employing spatial analysis (GIS) to evaluate various factors, including disaster risk, road conditions, materials, types, and proximity to land uses. The study identifies three vulnerability zones: low, medium, and high, with a high concentration of highly vulnerable roads in coastal areas. It emphasizes the need for infrastructure resilience and a holistic approach including design, materials, maintenance, and disaster preparedness. Land use also plays a role, with commercial and residential zones facing higher vulnerability. The study recommends material upgrades, enhanced maintenance practices, increased road capacity, and integrating disaster risk into spatial planning. Overall, this research contributes to the knowledge base of road network vulnerability, offering valuable insights for disaster mitigation strategies to improve the sustainability of vulnerable regions like Padang City

Resilience has increasingly become a crucial topic to the function of various real-world systems as our planet undergoes a rising trend of uncertainty and change due to natural, human and technological causes. Despite its ubiquitous use, the term resilience is poorly and often inconsistently used in various disciplines, hindering its universal understanding and application. This study applies the resilience system interpretation framework, which defines resilience irrespective of its disciplinary association, in the form of adaptation and adaptive systems, to two traffic flow systems. The system framework defines resilience as the ability of the system state and form to return to their initial or other suitable state or form through passive and active feedback structures. Both components of the system framework are demonstrated through practical simulation scenarios on the modified viscous Burgers’ equation and the LWR-Greenshields model equipped with an adaptive Extremum seeking control, respectively. This novel and systematic understanding of resilience will advance resilience analysis, design, and measurement processes in various real-world systems in a unified fashion and subsequently pave the way for resilience operationalization and its integration into industry standards.

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.
