Abstract

This thesis comprises two interconnected research areas addressing seismic analysis. The first part focuses on fault modelling in the Northwestern Himalayan region, aiming to characterize stress concentrations and gain insights into seismic activity. By examining fault geometries, interactions, and mechanism, this research contributes to a better understanding of seismic hazards in the region. The second part of the thesis investigates the impact of sedimentary basins on tall structures, specifically analysing a tall structure in Los Angeles using physics-based ground motions. Due to the limited availability of ground motion data for the Indian scenario, this study employs physics-based earthquake simulations for the Los Angeles basin. By evaluating the behaviour of the tall structure under these simulated ground motions, the thesis aims to assess the influence of sedimentary basins on structural response. Furthermore, the study includes a qualitative assessment of non-structural damage in the tall structure, considering the vulnerability of non-structural elements, such as partitions and equipment, to basin-induced ground motions. This assessment provides valuable insights into the effects of basin-induced ground motions on tall structures, guiding the development of effective mitigation strategies. In summary, this thesis presents a comprehensive analysis of fault modelling in the Northwestern Himalayan region and investigates the impact of sedimentary basins on tall structures using physics-based ground motions. The findings contribute to a better understanding of seismic hazards and the behaviour of structures in seismically active regions, informing future seismic design practices and enhancing the resilience of tall structures.
