“…This difference is predominantly due to the kinematic loading effects as discussed in the earlier section. For pile groups under lateral loading conditions, Brown and Shie (1990), Ng et al (2001) and Basile (2003), among others, reported that the shadowing effects will become less significant with the increase in pile spacing in pile groups. However, for piles under seismic loading conditions, though the pile-soil-pile interaction reduces with the increase in pile spacing, the group shadowing effects can still be predominant in widely spaced pile groups due to the significant kinematic loading effects.…”

“…The pile group and the single pile are modeled using a three-dimensional finite element software MIDAS GTS-NX. The Mohr-Coulomb (MC) and the Modified Mohr-Coulomb (MMC) constitutive models are used in simulating the soil behavior in the models using the soil parameters in table (1). The soil's relative density (Dr) is calculated using Kulhawy and Mayne's [9] (Equation 1) based on the SPT results, the angle of internal friction (ɸ) of sand is estimated using the API correlation [10] by (Equation 2), the soil young's modulus is computed using Bowles's [11] (Equation 3) Dr = (Equation 1) ɸ = 16Dr 2 + 0.17Dr + 28.4 (Equation 2) where, (ɸ) is the internal friction's angle, and (Dr) is in fraction.…”

“…Recently, three-dimensional numerical analysis has become a reliable method in studying geotechnical problems. Numerical studies concerning pile groups and soil-pile interactions are discussed by many researchers [1][2][3][4]. Brown et al [1] found that the pile group efficiency under lateral load is affected by the piles' spacing.…”

“…Ως διάταξη των πασσάλων επιλέγεται η s/D=10, δηλαδή η αξονική απόσταση των πασσάλων να είναι s=10D=10m. Η απόσταση αυτή είναι αρκετά μεγάλη ώστε η συμπεριφορά του μοντέλου να προσομοιώνει έναν μεμονωμένο πάσσαλο (Brown and Shie, 1990) με σκοπό να μελετηθεί μόνο η επιρροή των ορίων του μοντέλου χωρίς την επίδραση των γειτονικών πασσάλων.…”
