Scenario-based seismic loss estimation for concrete buildings in the central US

This paper focuses on the estimation of economic losses related to structural damage for concrete frame structures due to seismic events. A scenario-based assessment is conducted for moderate to high intensity earthquakes in the Central U.S. The scenario earthquakes under consideration have three magnitudes (5.5, 6.5, and 7.5) and Shelby County, Tennessee, is selected as the case study area. The buildings considered are typical Reinforced Concrete (RC) moment frame buildings in this region. Fragility curves developed using story-specific demand models are used to represent seismic vulnerability of the buildings. The structural damage of the selected buildings is assessed with a probabilistic approach that uses empirical structural damage factors and accounts for the prevailing uncertainties. Finally, these inputs are implemented into MAEviz, the seismic loss assessment software developed by the Mid-America Earthquake Center, and the structural losses for the concrete frame buildings are estimated. 2011 Taylor & Francis Group, London.
