Item Numerical Simulations for Seismic Response of Laterally Loaded Pile Foundation(Springer Science and Business Media Deutschland GmbH, 2024) Barik, T.; Chaudhary, B.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.Item Responses of Laterally Loaded Piles in Multi-Layered Sand: Numerical Simulations(Springer Science and Business Media Deutschland GmbH, 2025) Barik, T.; Chaudhary, B.Pile foundations are widely used to support heavy engineering structures by means of load-transferring to deeper soil layers safely. Generally, piles under high-rise buildings, tall chimneys, towers, offshore structures, high retaining walls, etc. are subjected to strong lateral loads. When the soil profile consists of multiple layers, the lateral load responses of piles become complex. They may also affect the lateral load carrying capacity of the pile foundation. Due to this complexity in 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 to investigate the lateral load carrying capacity of pile foundation in sand under multi-layered conditions by means of Finite Element (FE) Numerical Simulations using PLAXIS 3D. In addition to it, several parameters are studied to better understand the effects of those parameters on the behaviour of pile foundation. It is found from the FE analyses that length and diameter of the pile and soil profile are majorly impactful to the load carrying capacity of the pile while the presence of a water table does not have a significant effect until it reaches the ground level. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.
