Selection of Residential Building Design Requirements to Achieve Community Functionality Goals under Tornado Loading

An essential aspect of community disaster recovery planning is understanding the recovery process and developing appropriate probability-based recovery simulation tools to account for interdependent systems of lifeline networks (i.e., water, electrical power, and transportation systems) with the building infrastructure. The objective of this study is to illustrate selection of residential design code changes that are needed to achieve the recovery goals of a virtual community. In the present illustration, the community goals are expressed in terms of functionality of the built environment. This paper focuses only on the electric power network and building clusters subjected to tornado loads. A single combination of design changes selected from three alternatives is demonstrated to achieve the functionality goals at key points in time during the recovery process.
