Towards Seismic Resilient Bridges on an Urban Mass Rapid Transport Network
Publication: Urbanization Challenges in Emerging Economies: Resilience and Sustainability of Infrastructure
ABSTRACT
India has history of devastating earthquakes and nearly 54% of area is vulnerable to earthquakes. Bridges being the critical links of any roadways transportation network are under threat of greater seismic risk. The present study evaluates the differences in risk assessment of bridges on typical rail mass transit system network consisting of pile-pier (i.e. considering soil-structure interaction) using incremental dynamic analysis and pushover methods. The fragility curves have been developed for three limit states and the probability of failure has been derived for a PGA of 0.24 g. The results using two methodologies have been compared in terms of reliability indices which highlight the need of appropriate selection of structural analysis method for assessing the reliability. This study will aid in evolving reliable design methodology thus ensuring the performance levels and more informed pre-disaster planning strategies to avoid seismic risk of bridges.
