Abstract
How to achieve disaster-resilient communities has been considered the emphasis by many research institutions engaged in disaster prevention and mitigation. The design approach based on seismic resilience for large-span space structure is still in the exploratory stage and not proposed clearly. There is also a lack of necessary assessment and resilient quantitative criteria whether the structure could continue to serve after earthquake. This paper presents a critical review of existing resilience methodologies and summarizes two-dimensional backbone of resilient strategies according to specific resilient processes that are suitable to large-span space structures. The authors propose a probabilistic approach respectively for the pre-damage and post-damage assessments of structurally seismic resilience of large-span space structures, containing uncertainties depending on unexpected damage and recovery process. The goal of the conceptual framework shows that it is of value to extend the potential seismic resilient design conception integrated with large-span space structures.
