The seminar addresses a new design methodology for civil engineering structures called "Resilience-Based Design" (RBD) which can be considered as the next generation of Performance-Based Design (PBD). Currently designers and engineers approach a structure without considering its interaction with the community. This interaction should be considered as an integrated part of the design process. The structure should be not be considered as an independent unit, but as part of a group of buildings using the "Portfolio Approach" which would allow a regional loss analysis. The concept of "housing units" is essentially moved to the one of "housing blocks" within this methodology. The goal of RBD is to make individual structures and communities as "resilient" as possible by developing technologies and actions that allow each structure and/or community to regain its functionality as promptly as possible. The fundamental concepts of community resilience are analyzed and a common reference framework is established which is based on the Population and Demographics, Environmental/Ecosystem, Organized Governmental Services, Physical Infrastructure, Lifestyle and Community Competence, Economic Development, and Social-Cultural Capital (PEOPLES) Resilience Framework. Emphasis is given to hazard intensity measures, engineering demand parameters, and new performance levels are proposed for RBD. Some applications incorporating both performance and resilience objectives are shown in order to illustrate the feasibility of the proposed methodology for RBD.
