Abstract

The resilience of communities depends on the performance of the built environment and on supporting social, economic and public institutions on which the welfare of the community depends. The built environment is susceptible to damage due to a spectrum of environmental, geophysical, and anthropogenic hazards, which are characterized by large uncertainties in spatial and temporal domains. The performance of the built environment within a community depends on the integrated collective performance of its civil infrastructure, which is largely designed by codes, standards, and regulations. Advances in community resilience modeling and assessment will require a fundamental change in the way that code and standard-writing groups approach their tasks to ensure that performance and functionality of the built environment is consistent with community-wide resilience goals. The new design paradigm of performance-based engineering (or PBE) offers the framework for engineers and planners to achieve these desired levels of performance and functionality. Herein, we introduce, from a structural engineering perspective, some issues in developing and implementing performance-based design guidelines and practices aimed at achieving community resilience goals.
