“…Specifically, the axial force and displacement of the central pile are most affected by other piles, while piles farther away from the central pile are least affected by others [18,19]. Therefore, the relevant characteristics of the central pile become representative analysis objects when studying the load transfer rules and variable stiffness leveling design of composite foundations [20,21].…”

Composite foundations have been widely used and promoted in practical engineering applications. However, research on the joint-bearing mechanism of piles and soil within composite foundations is still not comprehensive enough. This paper proposes a method for calculating the additional internal forces of piles and soil within composite foundations. Based on a three-dimensional finite element analysis, this study investigates the variation patterns of the stress, displacement, and additional internal forces of piles and soil in the depth direction under the action of upper loads when using friction piles and end-bearing piles. This research aims to reveal the bearing performance of piles and soil. The results showed that, under the same conditions and due to the presence of end-bearing effects, the internal forces experienced by the entire pile body of the end-bearing piles were more uniform, exhibiting significant advantages in resisting deformation and being able to withstand larger loads. Additionally, the diffusion mechanism of the vertical forces, stresses, and displacements of piles and soil is discussed. Due to the negative frictional resistance of soil and the influence of pile end-bearing effects, the distribution of internal forces and the displacements of piles and soil exhibited different characteristics. This study provides a scientific reference for the theoretical analysis and design of composite foundations.

“…To date, the pile-raft foundations are one of the most effective developments in the foundation engineering field [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. They successfully apply in the design of multi-storey facilities on sites with unfavorable geological conditions, so far as they have an increased bearing capacity [2,[20][21][22][23][24]. However, in recent times, it is quite often in the construction of such foundations, there are cases of deviation from design solutions, which can lead, despite their high distribution capacity, to the uneven settlements development and, as a result, damage to the above-ground structures [1,3,[9][10][11][12][13][14].…”

During the building reconstruction with floors addition, there is a need to evaluate the building frame and foundation soil bearing capacity, especially if there are deviations from the design parameters. As a result of the field and numerical studies, we determined the basic change patterns in the stress-strain state of the 12-storey building load-bearing structures with a monolithic reinforced concrete frame due to uneven pile foundation deformation. We also found the influence degree of the existing deviations from the design parameters to the structures bearing capacity. The research results can be applied in reconstruction conditions with a significant increase in the load on the existing load-bearing elements of the building and on the pile foundation.
