Functionality and recovery are important resilience attributes but not considered in existing building design and assessment approaches. The study presents different resilience-based metrics based on probabilistic seismic resilience assessment of an archetypical IS code-conforming reinforced concrete building to gain insight in their repair cost, functionality, and recovery performance. This study uses the performance-based earthquake engineering framework. Assessments are conducted for several intensities ranging from return periods of 50 to 9975 years. The results reveal that the IS code-conforming building meets collapse prevention and life-safety objectives. However, time for reoccupancy after a design-level event is about 13 days, while it takes 6 months for functional recovery which may not be acceptable for critical buildings. The study shows that including functionality and recovery-based objectives is essential for design of such buildings. |
