Abstract:
Earthquakes pose a significant threat to structures, particularly when buildings are closely spaced. Seismic pounding occurs when nearby high-rise buildings collide due to differences in their dynamic vibrations, leading to potential structural damage that may compromise the building's safety. The rise of multi- story buildings in urban areas, driven by urbanization and population growth, increases the risk of seismic pounding. Despite building design safeguards, these structures often fail to account for the severe impact of seismic pounding, especially in densely populated metropolitan cities. The study addresses the lack of a precise database to understand and mitigate the issue of seismic pounding. The interaction between structures during earthquakes remains poorly understood, and there is no established solution to manage the effects of pounding in urban environments. The thesis aims to enhance the understanding of seismic pounding by analyzing the structural interaction between nearby buildings during earthquakes. Using time-history modeling and analysis, the study evaluates building separation lengths and design factors, providing recommendations to reduce pounding and improve structural resilience. The study also seeks to identify structural issues that contribute to seismic pounding and guide improvements in building design. A comparative analysis of lateral force-resisting systems, such as shear walls and bracing systems, will be conducted to assess their effectiveness in reducing structural weaknesses. The overall goal is to enhance seismic design practices by focusing on the complex dynamics of seismic pounding. This study provides practical recommendations for improving the seismic resilience of multi-story structures in earthquake-prone areas, using models developed with ETABS software in compliance with Indian Standard Codes IS456 for reinforced concrete design, IS800 for steel design, and IS1893 for earthquake-resistant design.
