Numerical Simulations for Seismic Response of Laterally Loaded Pile Foundation

Abstract

Pile foundations are frequently used to safely transfer enormous loads from superstructures to deeper soil layers in order to support structural weight. Due to earthquakes, piles are subjected to dynamic loadings, which causes significant damage to the foundation as well as the superstructure. Laterally loaded piles vulnerable to earthquakes have a complex dynamic reaction. Earthquake motions shake the foundation ground which can make it unstable. Due to this unpredictable behaviour, the research has been carried out for the last few decades on it but still the behaviour is not understood completely. Therefore, an attempt has been made in this study to investigate the dynamic response of the pile foundation due to earthquakes by performing numerical study using Finite Element (FE) program, PLAXIS 3D. In addition to it, several parameters have been studied to understand the effects of several parameters like soil properties, earthquake features (acceleration, frequency etc.) on pile behaviour, considering soil-pile interaction. It can be stated that this numerical simulation will be useful for the researchers and practicing engineers working on this domain. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.
