Special Issue Information

Dear Colleagues,

We are pleased to present this Special Issue on the seismic resilience of urban environments.

Overall, current seismic design infrastructure codes are primarily aimed at protecting human life, which has been successfully observed in recent large earthquakes in countries with developed engineering and construction practices, such as Chile and New Zealand, where the number of fatalities due to collapsed infrastructure is relatively low. Although repairable, several infrastructure systems exhibit seismic damage, compromising their functional and operational continuity as well as generating significant environmental impacts and economic losses, which strongly affects the resilience of the urban environments where these systems operate.

The seismic resilience of our urban environments can be described as the ability of our infrastructure to rapidly and efficiently cope with the impacts derived from seismic activity. Communities are currently demanding more than structural safety, where resilience should be oriented at minimizing environmental impacts, downtime and economic losses, but evaluated in life-cycle terms.

Consequently, in this Special Issue, we invite you to submit works that combine both sustainability as well as the seismic resilience of infrastructure, addressing topics such as: (i) the performance-based seismic design of new infrastructure, especially with the incorporation of life-cycle design goals (e.g., environmental impacts, downtime and economic losses); (ii) the performance-based seismic retrofit of existing infrastructure; (iii) the development/assessment of new materials/structural systems for improved seismic performance, evaluated in life-cycle terms. Some other possible topics are indicated in the keywords above, but please note that this list is not exhaustive.

We look forward to receiving your contributions.

Demands to advance toward more resilient and sustainable cities in terms of reducing casualties, economic losses, downtime, and environmental impacts derived from earthquake-induced damage are becoming more frequent. Indeed, accurate evaluations of the seismic performance of buildings via numerical simulations are crucial for the sustainable development of the built environment. Nevertheless, performance estimations could be influenced by alternative probabilistic methods that can be chosen throughout the procedure of building-specific risk assessment, specifically in the construction and validation of fragility functions. This study evaluates the numerical impacts of selecting different probabilistic models on seismic risk metrics for reinforced concrete dual wall–frame buildings. Specifically, alternative probabilistic models are implemented and evaluated for (i) the identification and elimination of unusual observations within the simulated data (i.e., outliers); (ii) the selection and implementation of different Probability Distribution Functions (PDFs) to estimate fragility functions at different limit states (LSs); and (iii) the application of goodness-of-fit tests and information criteria to assess the validity of proposed PDFs. According to the results, the risk measures showed large variability at the extreme building LS (collapse). On the other hand, for a lower LS (service level), the measures remain similar in all the cases despite the methods selected. Further, the variability observed in the collapse response is up to two times that after eliminating data outliers. Finally, the large variability obtained with the evaluated alternative probabilistic modeling methods suggests re-opening the technical discussion over the state of the practice often used in earthquake engineering to improve the decision-making process, mitigating earthquake-induced consequences in an environmentally, economically, and socially beneficial manner.
