From Performance to Resilience-Based Design of Structures - Keynote Lecture

The goal of Resilience‐Based design (RBD) is to make the built environment and the communities as “resilient” as possible, developing technologies and actions that allow each structure and/or community to regain its functionality as promptly as possible. The fundamental concepts of resilience are analyzed and a common reference framework is established for measuring community resilience at different spatial and temporal scales. Seven dimensions have been identified for measuring the community resilience. Each dimension is characterized with a corresponding performance metric which is combined with the other dimensions using a layered approach. The framework can be used to measure community resilience against any type of extreme event both during the emergency and in the long term post‐disaster phase. Several applications of the framework can already be found in literature for different types of infrastructures. In the long term, the proposed framework can be used as a decision support software to be used by decision makers and to help planner in selecting the optimal restoration strategy and enhance the community resilience index.
