Generating Site-Specific Ground Motions for Delhi Region for Seismic Vulnerability Assessment of Buildings—Promoting Disaster Resilient Communities
Publication: Urbanization Challenges in Emerging Economies: Resilience and Sustainability of Infrastructure
ABSTRACT
In this paper, synthetic ground motions are simulated employing a physics-based simulation methodology (PyLith), for a hypothetical earthquake of Mw 7.1 along one of the most active fault near Delhi region, Mahendragarh-Dehradun Fault (MDF). Further, using the synthetics, incremental dynamic analysis (IDA) is conducted on a typical six story concrete moment resisting frame building and IDA curves are constructed with residual drift ratio (%) versus spectral acceleration at fundamental period [Sa (T1, 5%)]. Furthermore, analytical fragility curves are derived for each damage state based on FEMA P-58, for determining the seismic performance of concrete frames in the event of an earthquake in the study region. The results reveal that at Sa (T1, 5%) of 1.0 g, there is an 86% and 68% probability of non-structural damage and slight structural damage respectively. Also, for Sa (T1, 5%) value of 1.5 g, there is more than 60% probability of exceedance of all damage states.
