According to practical situation, there have been limited investigations on the response of piles subjected to combined loadings especially when subjected to cyclic lateral loads. Those few studies led to contradictory results with regard to the effects of vertical loads on the lateral response of piles. Therefore, a series of experimental investigation into piles in dense sand subjected to combination of static vertical and cyclic lateral loading were conducted with instrumented model piles. The effect of the slenderness ratio (L/D) was also considered in this study (i.e. L/D= 25 and 40). In addition, a variety of two-way cyclic lateral loading conditions were applied to model piles using a mechanical loading system. One hundred cycles were used in each test to represent environmental loading such as offshore structures. It was found that under combined vertical and cyclic lateral loads the lateral displacement of piles decreased with an increase in vertical load whereas it causes large vertical displacements at all slenderness ratios. In addition, for all loading conditions the lateral, vertical (settlement and upward) displacements and bending moments increased as either the magnitude of cyclic load or the number of cycles increases.

“…According to the authors, these limited studies were not covered most of the pile foundation conditions that usually influence on the lateral pile performance under such loading condition, such as pile cross section, pile slenderness ratio, and soil density, especially by using laboratory program. The number of limited studies, including the pile performance under combined loading such as Karthigeyan et al 2006&2007, Rajagopal and Karthigeyan 2008, Abbas et al 2010, 2015and 2017 In the present study, the effect of pile cross sections on the behavior of it under combined loads was investigated with into consideration some parameters like: the values of combined load, the slenderness ratios of the pile, and pile materials.…”

In the present study, the effect of pile cross section on the lateral behavior of pile when subjected to combined loads has been investigated. The lateral tip displacement, as well as the deformation along the pile depth, has been taken into account. To achieve the objective that obtains from this work, the laboratory work was developed, which included piles made from aluminum and steel materials with circular and square cross-sections for each one. The diameter and the corresponding width of a square section of the used piles were 15 mm, with a slenderness ratio (L/D) of (25 and 45) and embedded in sandy soil with a relative density (Dr) of 70%. The test results revealed that the pile with square cross section was more resistance to lateral load compared with the traditional shape, with improvement in the range of (30-65%) in different condition. Also, the presence of axial load effect on the lateral response of piles.

“…Other investigations have attempted to study the lateral response of pile under pure lateral load using the finite element approach [9,11,16,23,24]. In addition, the influence the lateral pile response in 3D finite element approach when the pile carried both axial and lateral loads was studied by [12,13] and [1,2].…”

A three-dimensional finite element technique was used to analyse single pile lateral response subjected to pure lateral load. The main objective of this study is to assess the influence of the pile slenderness ratio on the lateral behaviour of single pile. The lateral single pile response in this assessment considered both lateral pile displacement and lateral soil resistance. As a result, modified p-y curves for lateral single pile response were improved when taking into account the influence lateral load magnitudes, pile cross sectional shape and flexural rigidity of the pile. The finite element method includes linear elastic, Mohr-Coulomb and 16-nodes interface models to represent the pile behaviour, soil performance and interface element, respectively. It can be concluded that the lateral pile deformation and lateral soil resistance because of the lateral load are always influenced by lateral load intensity and soil type as well as a pile slenderness ratio (L/D). The pile under an intermediate and large amount of loading (in case of cohesionless soil) has more resistance (low lateral displacement) than the pile embedded on the cohesion soil. In addition, it can be observed that the square-shaped pile is able to resist the load by about 30% more than the circular pile. On the other hand, pile in cohesionless soil was less affected by the change in EI compared with that in cohesive soil.
