Nonlinear 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...
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 کاملThree-dimensional Finite Element Modelling of Dynamic Pile–soil–pile Interaction in Time Domain
Dynamic analysis of embedded foundations like pile groups have received considerable attention in the past. Most existing approaches are established in the frequency domain, not allowing the simulation of material and geometric nonlinearities. In this paper, transient analyses are conducted to calculate the impedance of piles and pile groups, using a full three-dimensional numerical model for b...
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...
