DYNAMIC RESPONSE PREDICTION- dynamic and static conditions, (i.e. 2,4,5,6,7,12). Figure 1 shows one unit of the proposed Winkler soil model. The near-field element consists. of a complex spring and consistent mass, and represents the soil in the vicinity of the pile where a.
strong nonlinearity is induced by the pile shaft displacement. the dynamic behaviour of pile groups, which was observed to be a strongly frequency de-pendent [4, 5].
These findings, along with the increasing interest in soil-structure interaction, have led researchers to develop further analytical methods for modelling the dynamic behav-iour of pile groups [6, 7]. The analysis of the dynamic response of pile foundations to earthquake shaking is a complex problem and has been treated using concepts developed from the theory of elasticity, applicable to low level shaking, and to models incorporating non-linear soil response appropriate for stronger shaking intensities.
A review of available field reports indicates that due to the lack of complete. foundations has reached a point of satisfactory analysis of pile dynamic behavior have been developed.
These approaches provided a much response of pile supported buildings and structures. The impedance functions are defined as amplitudes of harmonic forces (or moments) that have to be applied the pile head in order.

Notable aspects of the analytical method used for this simulation include consideration of the nonlinear load‐deformation characteristics of pile elements, the dependence of the rotational stiffness at the pile head on the axial load, and the nonlinear behavior of soil spring including the pile group effect.
This chapter describes recent analytical and numerical advances in the modeling of the axial nonlinear dynamic interaction between a single pile and its embedding soil. On one hand, analytical solutions are developed for assessing the nonlinear axial dynamic response of the shaft of a pile subjected to dynamic loads, and in particular to.
A semianalytical method is developed to obtain the dynamic response of laterally loaded piles in a multilayered soil. In the analysis, the soil is modeled as a three-dimensional viscoelastic continuum with frequency-independent hysteretic material damping and the pile as a circular elastic Timoshenko beam.

61– On this basis, the impedance function at pile top is derived by amended impedance function transfer method proposed in this paper. Then, the velocity response at pile top can be obtained by means of inverse Fourier transform and convolution theorem.
The effects of pile–soil system parameters are studied, and some conclusions are proposed. The seismic design of pile foundations is currently performed in a relatively simple, deterministic manner. This report describes the development of a performance-based framework to create seismic designs of pile group foundations that consider all potential levels of loading and their likelihoods of occurrence in a particular area.
dynamic pile-driving formulas are being used for this purpose in building codes and specifications. The intent of this paper is first to review basic forms of the dynamic pile-driving formulas and the assumptions on which they are based. Then, a parameter study will be presented comparing 3 typical pile-driving formula solutions with corres.

Piles are long and slender members which transfer the load to deeper soil or. A simple method to estimate the equivalent stiffness of the foundations resting on any multilayered soil system is presented. Obtaining stiffness from the proposed method and using different values of the damping factor ranging between and %, the dynamic response of a foundation resting on a layered soil system is computed.

Liam Finn Abstract: A quasi-three-dimensional finite element method of analysis is proposed for the dynamic response analysis of pile foundations that is computationally feasible for practical applications.
dynamic response of foundations (Bhatia, ). Based on the scientific investigations carried out in the last few decades it has been established that it is not enough to base the design only on the vertical loads multiplied by a dynamic factor, even if this factor introduces a dynamic load many times greater than the original one.

Beginning with the earliest model of a single pile, adapted from those for embedded footings, it charts the development of the four pile-modeling techniques: the “dynamic Winkler-foundation” approach that uses springs to represent the effect of the soil; elastic-continuum-type formulations involving the analytical solutions for.
The case studies conducted thus far and described in the paper indicate that the proposed mathematical model works very well and that the statnamic test may become a useful tool for pile capacity prediction.
Key words: piles, pile driving, dynamic response, dynamic tests, bearing capacity. Pile Foundations are an essential basis for many structures. It is vital that they be designed with the utmost reliability, because the cost of failure is potentially huge.

Pile foundations are used as medium between unstable soil and solid ground in order to initiate construction of solid structures like building, pillar, etc. These pile foundations exhibit different behavior in different physical conditions and external factors.
Hence, the pile foundation behavior has been a subject of research for a long time. Pile Supported Foundation (Pile Cap) Analysis and Design Based on a geotechnical study, a pile supported foundation is required to support a heavily loaded building column.
Design the pile cap shown in the following figure with 12 in. diameter piles and a service load capacity of 50 tons each. I have modelled a building on pile and took two cases one with acceleration time history as input motion with one joint soil spring and another after ground response .Piles are relatively long and slender members used to transmit foundation loads through soil strata of low bearing capacity to deeper soil or rock having a higher bearing capacity.
The method by which this occurs is the basis of the simplest pile type classification. We have two main Pile Types (Classification of Piles): 1. End-Bearing piles, 2.Dynamic response of pile foundations has been studied for many years with different models ranging from distributed Winkler springs to advanced analytical solutions.
Special features in the dynamic impedances of pile foundations, which are mostly related to the group effect or pile-soil-pile interaction, have inspired researchers to develop special computational tools for capturing these.
