| Title of the article | Influence of concrete vibrocreep on pile settlements of slab-pile foundation |
| Abstract. | Abstract Problem statement. The aim of this work is to study the additional settlement of slab-pile foundation under cyclic loading due to the compression of the reinforced concrete piles taking into account the redistribution of efforts between the reinforcement, concrete, piles and the surrounding soil. There are no research results on this issue in the literature. Results. We carried out theoretical studies, considered the redistribution of efforts between the main elements of the slab-pile foundation. The article considers the change in the stress-strain state of a compressed reinforced concrete element due to the appearance of deformations of concrete and reinforcement vibrocreep in coherent conditions. Based on the research, we proposed the equation of changes in stresses and constrained deformations of concrete and reinforced concrete pile reinforcement under cyclic loading to develop the method for calculating the settlement of a slab-pile foundation. Conclusions. The significance of the results for the construction industry is that for the first time the proposed method allows us to estimate the settlements of the slab-pile foundation due to compression of the pile under cyclic loading. It is a significant contribution to the theory of pile foundations calculation and provides concrete saving of up to 15 % compared to the standard method. |
