        abstract = {Pile stiffness critically governs seismic performance of structures through soil-pile-structure interaction (SPSI), affecting parameters like base shear, drifts, and natural periods. This review synthesizes 2016-2026 studies on flexible, semi-rigid, and rigid piles, examin-ing influences of diameter (450-900 mm), seismic zones (II-V), and soil types (soft clay to dense sand). Numeri-cal models (STAAD.Pro, FLAC, 3D FE) and shake-table tests reveal rigid piles reduce superstructure set-tlements by 30-50% but amplify bending moments via inertial transfer, while flexible configurations elongate periods in soft soils. Key findings highlight nonlinear p-y effects, group efficiency, and near-fault pulse im-pacts. Gaps persist in code provisions (IS 1893:2002) for SPSI and high-rise applications. Recommendations advocate diameter-optimized designs balancing safety and economy, informing resilient foundation strategies in earthquake-prone regions.},
