ABSTRACT
Pile foundations play an essential role in transferring structural loads from superstructures to bedrock or stable soil layers. Dynamic instability of pile foundations, particularly under seismic events, poses significant risks, potentially leading to property damage, structural collapses, and loss of life. This research aims to investigate the impact of climate change on the dynamic stability of pile foundations, focusing on the influence of temperature variations during dynamic events. The study begins with the derivation of the equation of motion for a pile foundation subjected to seismic forces, incorporating the thermal properties of materials. To analyze dynamic stability of piles, the Bolotin method in terms of harmonic balance is employed to construct analytical stability diagrams. A numerical approach is developed to study the stability behavior of piles. A parametric study is then conducted, examining key factors such as temperature variations, damping, and excitation frequencies on the pile’s stability.
