| Title of the article | Behavior of plate-pile foundations models under cyclic loading |
| Abstract. | At high load levels on the ground or adverse ground conditions, one way to increase the carrying capacity is the use of plate-pile foundations. Buildings and structures and their foundations, along with static exposed to various types of cyclic loads, which in many cases are the main determinants security and integrity of the building elements. The joint deformation of the «pile – slab grillage – ground between pile» with regard to redistribution of effort between the individual elements in the process of cyclic loading is practically unknown. In this regard, the authors conducted experimental research models plate-pile foundations under cyclic loading. Our studies have established the basic laws of deformation of plate-pile foundation – soil of between pile space. Change efforts in the piles are located in specific zones of plate-pile foundation are shown in this work. As can be seen from there loading does not lead to an increase in effort in piles. Nature of the change effort in piles shows the redistribution of effort from the piles into the ground between piles. Under the action of cyclic loading is increased sediment basement up to 30 % compared to the first dive, effort and stress in piles in the ground of between pile space. Cyclic loading reduces the carrying capacity of 66,7 % based on 2500 cycles compared with static loading. Neglect the influence of cyclic loading in the engineering of plate-pile, pile foundations can lead to excessive strain and loses stability of the base. |
