| dc.description.abstract | Investigating the effects of lateral loads in design of foundation is important as compared to axial loads, although it gets normally less consideration in the usual practice. This study investigates the behavior of group piles in terms of load - displacement curves for trailing, intermediate and leading rows when it is laterally loaded by using FEM analysis employing Plaxis 3-D FOUNDATION. Mohr-Coulomb model has been used to model the soil material. A 15-noded triangular element is executed while 3-D meshing for soil material. The soil parameters were taken from previously done thesis, which has been calibrated from local soil property. Structural materials were modeled by using linearelastic model, since steel and concrete behaves elastically under loading. Parameters which has been considered were pile geometry such as pile length/depth, spacing and pile number (number of rows) with different loading step. In addition, the pile is fixed head system, but the effects of pile cap have not been considered, only used for distributing lateral loads equally. It has been found out that pile group lateral deformations are small when the pile spacing is large enough, while the number of piles in the group increases, lateral movement of leading rows are decreasing. This is due to the overlapping shearing zones of the intermediate rows. When depth of piles increases there is increment of lateral confinement because of the increment of over burden pressures. It is concluded for the laterally loaded group of piles; the leading rows can resist more reaction loads from the soil than the trail rows and deformed less than the trail and intermediate rows. Finally based on the parameter analysis the difference of row displacement of leading, intermediate and trailing row were from 4% up to 8%, 9% up to 14%, 15 up to 20% respectively of total pile movements. | en_US |
