Effect of Soil Properties on the Structural Response of Laterally Loaded Piles

EasyChair Preprint 7750

Abstract

Piles in offshore structures are vulnerable to lateral loads induced by high wind effects in coastal regions in addition to axial loads from the dead weight of the structure itself. Earthquakes are another source of lateral loads on piles in structures like bridges, dams, and high- to moderate- rise buildings. This study addresses the effect of soil properties around the pile on the structural design criteria (bending moments, shear forces, displacements, and lateral earth pressure) in the piles under combined effect of axial and lateral loads. Two soil types were considered in this study; clay and sand with different stiffnesses for each. The study revealed that the maximum bending moment and maximum shear force induced within the pile sections increases as the soil stiffness increases for both of sand and clay soils. The study revealed that piles embedded in clayey soils exhibits an average higher buckling capacity than in sandy soils. The buckling load in clayey soil surpassed that of the sandy soil by a factor of 20. The study has also incorporated determination of the buckling loads for piles embedded in clayey and sandy soils.
