Application of the PEER-PBEE framework for probabilistic resilience assessment of a structural system

The PEER-PBEE framework, introduced and developed by researchers from the Pacific Earthquake Engineering Research (PEER) Center, is a simple yet valuable tool for the application of a performance-based earthquake engineering (PBEE) approach. The framework has been applied both to single facilities and infrastructural systems. In 2015, Broccardo et al. have closely investigated the PEER-PBEE framework in the context of seismic resilience assessment of civil systems. The key objective was to extend the use of the original framework in order to establish a viable and simple tool for aprobabilistic resilience-based earthquake engineering approach (RBEE). The probabilistic RBEE aims to set the basis for the implementation of resilient management strategies that can address predefined targets for a given hazard. The goal of this study is to build on this development and investigate its practical use for a realistic case study. In the first part, we review the PEER-PBEE framework by imposing the resilience of a facility as a final decision variable. In the second part, the framework is tested for three stories reinforce concrete building with two alternative structural configurations. The output of the analysis is the computation of resilience statistics, such as themean annual rate of exceedance of resilience loss. A comparison between the two different structural configurations and alternative recovery strategies are shown.
