ABSTRACT
This study undertakes an integrated seismic risk analysis for two key cities in Gujarat: Bharuch and Ankleshwer, aiming to provide a comprehensive understanding of their seismic vulnerabilities. Deterministic Seismic Hazard Analysis (DSHA) were performed to estimate the Peak Ground Acceleration (PGA) for each city, offering insights into the expected ground shaking intensity under various scenarios. The calculated PGA and structural response metrics were compared with the seismic design criteria specified in IS 1893:2016 to identify potential non-conformities and vulnerabilities. To aid visualization and interpretation, comparative graphs, seismic hazard curves, and zonation maps were prepared, illustrating spatial variations in seismic risk across the cities. The results highlight significant disparities in seismic demands relative to current design standards, underscoring the need for enhanced structural resilience and updated design practices. By combining regional hazard data with structural performance evaluations, the study offers a robust framework for improving earthquake resilience and mitigating risks in Gujarat’s urban centers, contributing to the safety and sustainability of these rapidly growing cities.
