Abstract

Mid-America is a region of moderate seismicity. Infrequent moderate to large events had occurred in the past and can occur again and cause large losses. The performance of the building stock and other structures under future earthquakes is a serious concern. The major threats of future seismic events come from the New Madrid Seismic Zone (NMSZ) and several other areas of moderate seismicity. As ground motion records of engineering interest in this area have been scarce, to evaluate the performance of buildings and structures and estimate loss/cost, simulation of future events based on current data and knowledge is necessary. A method of simulation is developed for this purpose. The method is based on the latest information of seismicity in this region, the most recent ground motion models and simulation methods appropriate for engineering applications in this region. A strong emphasis is placed on uncertainty modeling and efficiency in application to performance evaluation and fragility analysis. The procedure may be improved as more knowledge on earthquakes in this region and more accurate and efficient methods of ground motion modeling become available. A brief description of the method of simulation and results obtained for three Mid-America cities is given in the following.
