“…Open space is an agent for recovery and adaptation as a site of operational bases for reconstruction work. While at the pre-disaster time most actions are focused on retrofitting the built-up environment and lifelines [94][95][96][97], open space (as well as social community) contributes to resilience the most at the emergency response (evacuation) and during the reconstruction phase. On the other side it is important to plan ahead and thus ensure the restorative capacities of both open space and social community before the earthquake strikes.…”

For a city to perform successfully, and its citizens to feel safe and comfortable, the health of basic urban components and the overall resilience of the urban system is crucial. As the importance of the resilient urban system has been recognized in the scientific literature, many studies have been done on this topic. Therefore, to find out the gaps in the existing literature and the opportunities for further research, a new systematic literature review has been performed in three stages. Different bibliographic techniques (co-occurrence and co-citation analysis) have been applied and, in the final stage of the analysis, an in-depth study of the content of the selected papers addressing open space in relation to urban seismic resilience has been carried out. The obtained results and trends have shown a lack of research on the potential of open space for enhancing urban seismic resilience, as well as a challenge for its quantitative assessment. The ability of the affected resilient system is to achieve at least a pre-disaster performance level in an acceptable time, which can be gained, among others, by using the restorative potential of open space. Based on the synthesis of these findings the authors' draft model of an urban system integrating the potential of open space is presented in terms of a complex network theory.

“…With the assumption, the initial failure probability of each network case is: 75.33% for Case 1, 21.31% for Case 2, 53.45% for Case 3, and 49.90% for Case 4. For risk mitigation, the retrofit behavior of a bridge can be considered by scaling the median value of ground motion intensity in its fragility function [45,83]. In the example, the magnifications for medians are respectively assumed to be 155%, 175%, and 204% for slight, moderate, and extensive damage states, which corresponds to the full steel jacketing reinforcement [84,85].…”

“…Although all the above methods greatly reduce the computational effort, there could be a gap between their results and the real optimal solution because none of them takes into account the uncertainties in the damage states of network components. Several recent studies have proposed to evaluate the importance of components using conditional probability between component failure and system failure [42][43][44][45]. These methods consider both the vulnerability of a component and its impact on system reliability, which improves the identification of retrofit importance.…”

Seismic mitigation of transportation systems has become a worldwide challenge, because identifying an optimal retrofit strategy entails significant computational efforts, especially for large-scale networks with numerous candidate strategies and time-consuming risk assessment processes. An efficient joint importance-based methodology is proposed in this paper to address the challenge. The proposed method selects the component set (e.g., bridges) that is most decisive to the network seismic risk based on only one set of stochastic samples but takes into account the uncertainty of multiple damage states and the interactive effect between different components. The reliability and stability of the proposed method are verified on a hypothetical transportation network under different conditions.

“…These infrastructures are among the most strategic elements of transportation networks that have been constructed by crossing natural and artificial barriers and are more affected by the environment than other infrastructures related to this sector (Jakiel and Fabianowski, 2015). Wang and Jia (2020) investigated the importance of the transportation system in the human life and analyzed the existence risk in the transportation network. This paper examined the role of the bridge in the transportation system.…”

Given the advances in technology and the development of urban development and progress in people's lifestyles, the use of bridges is considered as an important and necessary way of esophageal communication. Bridges are one of the most important tools for connecting roads and different cities, which connect different areas and create connections between people. One of the most important and necessary measures in the bridge industry is related to the repair and maintenance of bridges, which cost less than building a bridge and help to create connections between people. To this end, the present study examines the effects affecting the maintenance and repair of bridges in urban contexts and for this issue an approach under conditions of intuitive fuzzy uncertainty based on analytic network process and comprise solution methods to calculate weights and option ranking offers. Finally, in order to validate the proposed method, a case study is used along with a comparison of the proposed method and existing methods in the literature. The final results indicate the strength and efficiency of the proposed method in calculating weights and ranking options for the project of maintenance and repair of urban bridges in Rasht.
