Additional Settlement of the Raft-Pile Foundation, Taking into Account the Deformations of the Pile Under Cyclic Loading
https://orcid.org/http://orcid.org/0000-0002-6193-0928
The aim of the work is to study the additional settlement of the raft-pile foundation under cyclic loading due to the deformation of the reinforced concrete pile material under the conditions of redistribution of the compression forces of the reinforced concrete pile, taking into account the redistribution of forces between the reinforcement and the concrete of the pile, as well as the pile and the surrounding soil. There are no research results on this problem in the existing literature. Theoretical studies are carried out and the redistribution of forces between the main elements of the raft–pile foundation is considered. The change in the stress-strain state of a compressed reinforced concrete element due to the manifestation of deformations of the vibro-creep of concrete and reinforcement under cohesive conditions is considered. Based on the research, the equation of changes in stresses and constrained deformations of concrete and pile reinforcement under cyclic loading is proposed for the development of a method for calculating the settlement of a raft-pile foundation. For the first time the proposed method allows us to estimate the settlement of the raft-pile foundation taking into account the deformation of the reinforced concrete pile and the compression of the pile under cyclic loading, which is a significant contribution to the theory of calculating pile foundations and provides concrete savings of up to 15% compared to the standard method.
