Modeling a “pile-soil array” system under the seismic load action taking into account shock-absorbing properties of the soil

Abstract

In this article, in a spatial setting, the modeling technique for a reinforced concrete pile immersed in the soil array under the seismic load action has been considered. Modeling of the “pile-soil mass” system elements is performed by the volumetric finite elements. The calculation includes the shock-absorbing properties of the soil mass model (“transparent boundaries”). A comparison of the proposed methodology with the known solutions has been performed. The prospects of further development and practical application of the pile operation proposed model together with the soil under the seismic load action has been given.

Investigation of the dynamic characteristics of the “building - pile foundation” system with the random parameters of foundation soils

“…Piles and soil mass are made of volumetric finite elements. The joint work of the pile and the soil massif is presented in the form of the "pile -soil massif" system according to [14]. To a depth at which the soil resistance along the lateral surface of the pile is not taken into account, two-node finite elements of the corresponding stiffness are installed , [15] with the work exclusively in the horizontal direction.…”
