چکیده
It is seen from recent earthquakes that in case of fixed-base foundation system, damped systems have proved to be longing the lifespan structure by lengthening lateral fundamental period leads higher damping comparison assumptions a system. In this study, better understand phenomenon involved soil-pile interaction finite element simulation model developed Abaqus FEA software. The numerical made for transient analysis follows Rayleigh's Damping Coefficient material damping. paper, rational Dynamic Response Short-Bored Pile subject axial load Finite Element Method. performed using CAE Soil media sand soil and clay with pile as Mild Steel RCC, combination each group incremental load. same FE studied used piles which results drastic change displacement pattern.

Vertical Vibration Analysis of Soil-pile Interaction Systems Considering the Soil-pile Interface Behavior
A numerical method is presented herein to study soil-pile interaction systems in a stratified media. The method is based on a coupling of the finite element method and the boundary element method. The near field is modeled by the finite elements whereas the far field is modeled by the boundary dement formulation using the multi-layer dynamic fimdamental solution that satisfies the radiation con...
متن کاملDynamic Pile-soil-pile Interaction. Part I: Analysis of Axial Vibration
Simple methods of analysis are developed for computing the dynamic steady-state axial response of floating pile groups embedded in homogeneous and non-homogeneous soil deposits. Physically-motivated approximations are introduced to account for the interaction between two individual piles. It is found that such an interaction arises chiefly from the ‘interference’ of wave fields originating alon...
متن کاملDynamic Interaction of Soil-Pile-Structure under Seismic Action
Due to randomness of seismic load, it is difficult to predict the complexity of the soil, pile, structures and their system. Presently, there isn’t a better way to explain and simulate the dynamic interaction of soil-pile-structure completely and precisely. Based on the stiffness expressions of interaction, the improved physical and mathematical models are setup to reflect the basic mass, stiff...
متن کاملDynamic soil±pile±foundation±structure interaction: records and predictions
The problem of soil±pile±foundation±superstructure interaction is examined, and a simple rational procedure to analyse the response of a structure supported on pile groups is presented. This procedure combines theories for the computation of the dynamic impedances and kinematic±seismic response factors of pile foundations with a multi-degree-of-freedom structural model. The procedure is applied...
متن کاملNonlinear Soil - Pile - Structure Interaction in Dynamic or Seismic Response
The stiffness and damping of pile foundations are proposed, which vary with the ratio of shear modulus Gi / Go to indicate the nonlinear properties of soil. The range of Gi / Go is defined with different vibration intensities for applications, and a computer program DYNAN is available based on the boundary zone model with non-reflective interface. Two engineering cases are studied to illustrate...
