ABSTRACT
Rapid recovery of functionality after disaster is an important attribute of resilient infrastructure. Modern code-compliant buildings are designed based on life-safety principles and may experience severe damage during earthquakes leading to loss of their use for long periods. Contributors to occupancy and functionality losses should be first identified for enhancing performance and developing resilience-based design guidelines. This study assesses economic, reoccupancy, and functionality losses and subsequent recovery for an archetypical building, considering performance of structural and nonstructural components under a probabilistic performance-based earthquake engineering framework. The study provides deeper understanding of the root causes of functional vulnerability of code-compliant buildings and opportunities to reduce. The contribution of various components to loss of immediate occupancy and functionality is evaluated and implications of various nonstructural improvements on different component-level and building-level resilience metrics are assessed. The study illustrates the necessity of explicit nonstructural design options to enhance seismic resilience of buildings.
