Abstract

Lateral earth resistance of pile cap is usually ignored in the design practice in the United States. This part of lateral resistance could be significant for a large pile group design, particularly when the lateral load controls the design. A method is presented to calculate the lateral resistance of the pile cap based on FEMA 356 and compared with an approach from the Chinese Design Code. With the consideration of lateral resistance of the pile cap, an optimum spacing is found for a large strip-shape pile group to provide maximum lateral resistance. This design approach is applied to a case study – a natural gas-fueled turbine power plant built near Nanjing City, China.

Large Pile Group Design Optimization with Lateral Resistance of Pile Cap

Arlington, Virginia

Lateral earth resistance of pile cap is usually ignored in the design practice in the United States. This part of lateral resistance could be significant for a large pile group design, particularly when the lateral load controls the design. A method is presented to calculate the lateral resistance of the pile cap based on FEMA 356 and compared with an approach from the Chinese Design Code. With the consideration of lateral resistance of the pile cap, an optimum spacing is found for a large strip-shape pile group to provide maximum lateral resistance.
