A Case Study for Modeling Interdependencies Between the Building Portfolio, Transportation Network, and Healthcare System in the Community

A multi-system model is proposed to simulate the interaction between the building portfolio, transportation network, and healthcare system of an earthquake-stricken community. The proposed simulation model and its capabilities are demonstrated through a case study that focuses on modeling the seismic resilience of a part of Shelby County, Tennessee. The building portfolio data was extracted from the database provided in Ergo-EQ software version 4.0 Beta 2. The studied area is approximately 14 km2 (5.4 mi2) with a population of approximately 40,000 which is considered a typical midsize community. The building portfolio consists of around 8600 buildings, mostly wooden that areas are typical of US residential communities.
