Abstract
The seismic performance of structures is significantly influenced by the type of foundation employed. This study investigates the effect of different foundation types on earthquake resistance through analytical and numerical methods, focusing on shallow foundations (spread footings and mat foundations) and deep foundations (pile foundations). Using seismic response data from past earthquakes and structural analysis simulations, the research compares the dynamic behavior, settlement characteristics, and lateral load resistance of various foundation systems. Statistical analysis highlights significant differences in performance parameters such as displacement, acceleration, and damage levels. The findings confirm that deep foundations provide superior resistance under high seismic intensity due to enhanced soil-structure interaction, while shallow foundations can be optimized for moderate seismic zones. This research aids in foundation selection to improve earthquake resilience in civil infrastructure.
