Assumptions involved in the design of pile.
Pile cap design online.
This article is intended to offer a brief introduction to the new crsi dfi concrete reinforcing steel institute deep foundations institute pile cap design guide referred to henceforth as the guide.
Calculate the dimensions of the pile cap.
Save as the safe f2k file generated as previously created to begin the modeling.
The axial loads on the column are due to dead and live loads and.
Diameter piles and a service load capacity of 50 tons each.
Marked pile cap layout.
Although pile caps are an important structural element they are generally neglected in textbooks on structural design.
Design the pile cap completely using c30 37 concrete with 500mpa high tensile steel assuming the column to be placed in the centroid of the pile group.
And the piles are embedded 4 in.
Size of the column on the pile cap 500x500mm.
Cover to the reinforcement 50mm.
Into the pile cap.
Design the pile cap shown in the following figure with 12 in.
Pile cap design provides advanced analysis design detailing and scheduling of pile caps with up to 9 piles supporting circular or rectangular columns.
The pile cap should normally be rigid so as to distribute the forces equally on the piles of a group.
Characteristic strength of steel as 500 n mm 2.
Academia edu is a platform for academics to share research papers.
Design load 3000 kn.
Kindly bear in mind that at the end of the day it is always the structural engineer s decision and judgment will still follow depending on your guts and prerogative but at least the above basic knowledge can help you dig in and explore pile cap designing.
In general it is designed like a footing on soil but with the difference that instead of uniform reaction from the soil the reactions in this case are concentrated either point loads or distributed.
Pile cap design allows you to interactively design the pile caps by integrating directly with the 3d structural model.
Modeling of pile cap in safe is then ready once you completed the designation of which types of pile cap to use in your foundation design.
Consider the design of a pile cap supporting two pile and a single column on the pile cap.
Pile cap modeling and design parameters assignment.
Geometry of the pile cap try an overall depth h 1000mm with an average effective depth of 900mm the spacing between piles 3 500 1500mm and assuming an overhang of 400mm both ways.

The above design assumptions and recommendations are considered as guidelines in considering pile cap as your choice of foundation.
