Comprehensive Review of Community Seismic Resilience: Concept, Frameworks, and Case Studies
Advances in Civil Engineering, Volume 2022, Issue 1, 2022., 2022 Seismic resilience is a concept to evaluate the postearthquake functionality of structures that significantly play a critical role in postearthquake rescue and recovery. Indeed, the community is made up of more than just buildings; it is also made up of other subsystems such as hospital and school facilities as well as roads, drainage systems, sewer ...
