The bearing capacity of a single pile in granular soil was analyzed piles under vertical loads in the study of the mechanism of shaft fiiction. The effect of the deformation modulus on the bearing capacity of the single pile in granular materials, and especially in sand, was examined. By using the FLAC program for the finite element analysis it was possible to predict quite accurately the load ...

Pile foundations is a well-studied technique with many applications and its benefits on structures have been widely studied in the literature. In particular, mutual effects of pile flexibility soil deformability may significantly modify seismic behaviour superstructures. order to consider uncertainties that are connected these issues, paper applies probabilistic-based approach fragility curves ...

This study aimed to investigate whether the seismic fragility and performance of interaction soil-pile-structure (ISPS) were affected by different parameters: axial load, a section pile, longitudinal steel ratio pile implanted in type sand (loose, medium, dense). In order better understand ISPS phenomena, series nonlinear static analysis have been conducted for two cases, namely: (i) fixed syst...

Piles and diaphragm wall supported berthing structure on marine soils are loaded laterally from horizontal soil movements generated by dredging. The literature on the adequacy of the finite element method modeling of berthing structure to analyse their behaviour during dredging and under earthquake condition is limited. This paper describes the finite element approach for analysing the lateral ...

The case studied in the paper proves that thickening the pile cap is an effective seismic retrofit alternative to strengthen a pile group foundation. Unlike the typical seismic retrofitting of foundation, the proposed method eliminates the need to drive long piles into existing bridge substructures, substantially reducing cost, construction time and traffic interruption. The method thickens the...
