Abstract
In recent years, the resilience assessment for bridges has drawn ample attention in the engineering and management community. It has been attempted to evaluate bridge resilience by developing a resilience matrix or single-measure index. However, existing studies overlooked the prevailing interdependency among various physical and social infrastructures. Moreover, the technical, organizational, social, and economic aspects of these infrastructures are of dynamic nature. Therefore, this study develops a causal loop diagram (CLD) of bridge resilience to explore and understand how other infrastructures and their dynamism influence bridge resilience. Total 21 bridge resilience factors are identified based on the literature review. Out of these, 14 bridge resilience factors are shortlisted by using the Delphi method. Along with these 14 shortlisted factors, four properties of resilience (robustness, rapidity, resourcefulness, redundancy) and four infrastructures (bridge, transportation network, other utility infrastructures, and governance system) are considered to develop CLD. Thus, eight causal loops are developed, validated, and presented for improving bridge resilience. Further, the proposed study can help to implement effective policies for improving urban resilience and developing a smart city digital twin (SCDT) system.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
