Seismic behaviour of piles in non-liquefiable and liquefiable soil

A. Fouad Hussein et al.

Summary: This study investigated the nonlinear soil-pile-structure interaction using three-dimensional nonlinear finite element models and verified them with large-scale shaking table tests. It evaluated pile responses in different soil conditions to ground motions with varying intensities, considering kinematic and inertial interaction effects. The study found that piles in liquefiable soil experienced significantly increased bending moments, with inertial interaction contributing the most to bending moments at the top and interface of piles.

Assessment of SSI effects on stiffness of single and grouped helical piles in dry sand from large shake table tests

A. F. Fayez et al.

Summary: Full-scale shake table testing was conducted to evaluate the seismic performance of single and grouped helical piles. It was found that the soil's disturbance increased as number of helices increased, leading to reduced pile-soil stiffness and natural frequency. Successive shakings resulted in decreased natural frequencies of single piles and pile groups, attributed to degradation in pile-soil stiffness and gap formation. These effects, including the resonance condition and gap opening, must be considered in seismic design of helical pile foundations. The software DYNA6 could accurately predict the behavior of single and grouped piles by accounting for soil stiffness degradation and gap opening.

Seismic response of nonlinear soil-structure interaction systems through the Preisach formalism: the Messina Bell Tower case study

P. Cacciola et al.

Summary: This paper addresses the seismic response of linear structures on compliant soil by applying the Preisach formalism to capture soil nonlinearities. The study explores the novel application of the Preisach model of hysteresis for nonlinear soil-structure interaction problems, focusing on the seismic response of a real structure - the bell tower of the Messina Cathedral in Italy. Through a harmonic balance procedure, simplified nonlinear springs and dashpots are derived for evaluating the nonlinear soil-structure interaction response accurately. Results show that the proposed Preisach lumped parameter model aligns well with the complete FE analysis, offering a promising strategy for nonlinear soil-structure interaction studies.

A probabilistic investigation on the dynamic behaviour of pile foundations in homogeneous soils

Minnucci Lucia et al.

Summary: Soil-structure interaction poses a complex problem in structural design due to difficulties in modelling the soil-foundation behavior. The paper presents a probabilistic perspective on the dynamic behavior of pile foundations in homogeneous soils, focusing on the uncertainties in impedance functions and kinematic response factors. Results show that output quantities are strongly influenced by frequency, with shear wave velocity being highly sensitive to system response. Sensitivity analyses reveal the significant role of soil density and pile elastic modulus, depending on foundation layout.

Numerical model for the dynamic and seismic analysis of pile-supported structures with a meshless integral representation of the layered soil

Guillermo M. alamo et al.

Summary: This paper introduces a three-dimensional linear numerical model for dynamic and seismic analysis of pile-supported structures, considering the interaction between structure, piles, soil, and seismic waves. By using advanced Green's functions to simulate the dynamic behavior of layered soils, the model simplifies representation and data preparation, allowing for complex soil profiles and problems with large numbers of elements. The seismic excitation is implemented through incident planar body waves, and the system response is evaluated in the frequency domain before obtaining seismic results in the time domain using the Fast Fourier Transform. An application example is presented to demonstrate the capabilities of the model, exploring the influence of soil profile and angle of incidence on variables of interest in earthquake engineering.

Summary: Pile-to-pile interactions increase the settlement of pile groups and may reduce group stiffness under static loading. The stiffness of pile groups under dynamic loading can either increase or decrease depending on loading frequency.
