“…Figure 3 shows that pile of 25.4mm diameter with 200mm free standing height behave as long-flexible pile and all other piles are comes under intermediate and short rigid piles. The effect of lateral load on socketed depth may not be significant in long flexible piles (Karthigeyan and Rajagopal, 2012) where the depth of soil is significant to resist the lateral load. Therefore, the present study is more focused on intermediate and short piles.…”

The structure has to be socketed into hard strata to enhance the efficiency of load carrying capacity for a substructure carrying heavy lateral load. In case of non-displacement piles, drilling the hard strata is a time consuming and expensive process. A system of experimental program was conducted on an instrumented model pile to study the behaviour of pile socketing under lateral load by varying its depth of socketing and the free standing height of pile above the ground level. The experimental results showed that increasing the depth of socketing significantly increases the lateral load carrying capacity of pile. At 3D depth socketing with 800 mm (L e /L=33.33%) free standing height, the capacities of 38.1 mm and 50.8 mm diameter piles were increased respectively by 4 and 8.23 times the capacity of 25.4 mm diameter pile. Compared with pile bearing over hard strata, socketing the pile into hard strata reduces the lateral displacements substantially

“…The engineering structures are subject to several sources of lateral loads, which vary based on the building's location, height, and other pertinent factors [3]. The lateral load capacity of a pile group is affected by the loading method, pile spacing, and soil type [4]. The cycles number, amplitude of cyclic and frequency, and loading also significantly influenced the pile capacities and displacements [5].…”

This paper presents the lateral static and cyclic response of a group of piles. The experimental program included this on a small scale using hollow piles of aluminium, and the sand rain method was employed to prepare the sandy soil with a 70% relative density. The case study is a laboratory model of a pile group 2x2 with spacing (i.e., 3D,5D, and 7D), and the proportion of embedded length to circular pile diameter (L/D) = 43. Different lateral cyclic loading ratios CLR of 60%, 80%, and 100% from pile group capacity are used. According to the experiments' results, the vertical and lateral piles' capacity and displacement are greatly impacted by the cyclic-loading variables, which include the number of cycles and the cyclic-load ratio. It can be concluded that when increases in CLR usually influence on pile group performance, and the lateral displacement increasing up to 66% for closely spaced piles. The pile group spacing affects the uplift displacement; the highest reach value (4.7mm) upward is 7D.

“…The distance between these piles, the source of loading, the soil condition, and other factors influence the group pile's ability to resist horizontal loads. (1) One-way lateral cyclic load also has greater effects on soil stiffness and strength at the front of the piles than at the back of them. (2) Previous studies have revealed that various parameters regulate the behavior of cohesionless soil under recurrent loading such as the level of stress, the relative density, the number of cycles, the confining of pressure, and the spacing of the pile.…”

In fact, most civil engineering projects are subjected to cyclic loads. The sources of this load are usually seismic, wind, sea waves, and others. Model tests in sandy soil were performed to determine the maximum bending moment at which a pile group (2x2) would respond under one-way lateral cyclic loading. The group pile was made of aluminum piles that were installed in sandy soil with a 70% relative density and three-pile spacing of (3D, 5D, and 7D). The cyclic loads ratio (CLR) used are (0.6, 0,0,8, and 1.0) that is a result from average lateral static load. It can be concluded that an increase in group pile spacing can reduce the maximum bending moment by up to 92%. In addition, As the distance increases, the bending moment decreases, the front pile group provides a greater maximum bending moment than the back rows, as the maximum value in comparison reached 53%.
