Validation of the use of synthetic near-fault ground motions to estimate the response of a concrete building in a risk assessment framework Dabaghi, Mayssa; Galanis, Panagiotis H.; Der Kiureghian, Armen; Moehle, Jack P.
In this study, the incremental dynamic analysis method or IDA (Vamvatsikos and Cornell, 2002) is used in the collapse performance evaluation of a reinforced concrete building subjected to near-fault ground motions. The analysis is performed for two sets of ground motions: (1) a recorded dataset based on FEMA P695 (2009); and (2) a synthetic dataset corresponding to the recorded one and generated using the parameterized stochastic model of near-fault ground motion by Dabaghi and Der Kiureghian (2014). The results show that the synthetic dataset tends to slightly underestimate the collapse capacity of the studied building compared to the recorded dataset. Despite this fact, the study demonstrates the potential of using synthetic ground motions in future applications of performance-based earthquake engineering.
