Pile Supported Foundation (Pile Cap) Analysis and Design. Based on a geotechnical study, a pile supported foundation is required to support a heavily loaded building column. Design the pile cap shown in the following figure with 12 in. diameter piles and a service load capacity of 50 tons each.
Geometry of the Pile-Cap. Try an overall depth, h=1000mm, effective depth =900mm. Spacing between pile = 3×400 = 1200mm. Overhangs from edge of piles = 150mm. Length of pile = 1200+400/2+400/2+150+150 =1900mm. Width of pile cap = 400+150+150 = 700mm.
In this tutorial it is explained how to use Nonlinear Finite Element Analysis (NLFEA) to determine the reinforcement design for a pile cap which complies with the Eurocode 2 (EC2)1 and the fib Model Code 2010 (fib2010)2. Eurocode 2 (NEN-EN 1992-1-1, 5.7) allows NLFEA:
selection, design, and installation of pile foundations. The guidance is based on the present state of technology for pile-soil-structure-foundation interaction behavior.
10 kwi 2024 · Designing pile caps according to ACI 318-19 is a critical aspect of foundation design in civil engineering. Pile caps serve as structural elements that distribute loads from columns or...
2 kwi 2018 · Pile cap under axial + moment (Beam Theory) A pile foundation is required to support an ultimate axial load of 4200kN and an ultimate bending moment of 75kNm from a 400x400 mm rectangular reinforced concrete column. The pile used is 300x300mm precast RC piles with service load capacity of 600kN.
This Standard provides a guideline for an engineering approach to the design and subsequent installation of pile foundations. The purpose is to furnish a rational basis for this process, taking into account published model building codes and general standards of practice.
