Analysis of Steel Chip Fiber Reinforced Composite Dual Pile Under Lateral Load Conditions on Sloping Terrain
Abstract: Pile foundations, in addition to supporting vertical loads from superstructures, are subjected to lateral stresses arising from seismic activities, wind gusts, water currents, and traffic impacts etc. Failure to account for these lateral forces can pose significant risks if the structure is expected to encounter any form of lateral pressure. Previous research has investigated the behavior of individual composite piles under horizontal forces, considering different soil properties, to determine the …

Piled Raft Design Approach for a High Rise Building on Tithal Road, Valsad, Gujarat
Abstract: ABSTRACTThe piled raft foundation has been efficiently used for the foundation of high rise structures. A typical high rise building generally imparts higher load on central core area due to existence of lifts, elevators and shear walls, comparison to the edge area. The shallow foundation may not control the settlement and the pile foundation cost may be expansive for the foundation of high rise structures. The piled raft foundation can …

Small-Scale Model Study on the Load-Deflection Characteristics of Single Piles under Static Lateral Load
Abstract: The capacity of a certain mathematical model to mimic a behavior occurring on a larger scale often concerns engineers. To evaluate a particular structure's safety factor, model uncertainty is an important consideration. Piles have been widely used to support axial and lateral loads for a wide range of structures, including high-rise buildings, transmission towers, power plants, offshore structures, highway and railway structures. Many transmission towers, high-rise buildings, highway and railway …

Evaluation of Equal Settlements of Geosynthetic Reinforced Piled Embankment
Abstract: Geosynthetic-Reinforced Pile-Supported Embankments (GRPSE) have emerged as an effective alternative to traditional geotechnical methods Constructing of piled embankments on soft soils. Design of pile-reinforced embankments and evaluation of plane of equal settlements is critical in the case of soft soils. If the embankment height exceeds the height of the plane of the equal settlements, settlements cannot be seen on the pavement, otherwise, differential settlements may be observed on the pavement. …

Numerical Simulation of Mitigation of Soil Swelling Problem under Communication Tower Using Helical Piles
Abstract: AbstractExpansive soils exhibit significant volume changes with variations in soil moisture content. Expansive soils are often considered as problematic soils. It undergoes large volume changes upon wetting and drying and causes huge damages to the structures resting on it. Numerical modeling was carried out by using PLAXIS 3D-2013 software, in which modeling the soil by using hardening soil model was done. Tower rested on expansive soils are subjected to uplift …

Efficacy of Strain Wedge Method Against Traditional p-y Method for Analysis of Piles Subjected to Different Load and Soil Condition: A Review
Abstract: Pile foundation plays a major role in design of structures as its lateral response dominates the design subjected to lateral loads. These loads acting on foundations may be sustained from traffic loading on a bridge pier or earth pressure in a retaining wall. As soil reaction and pile deflection affect each other for a lateral load, this becomes a very complex soil-structure interaction problem. There are many approaches or methods …
