Design of pile cap foundation

It typically shapes component of the base of a structure, normally a multi-story structure, construction or bearing foundation for weighty furnishings. The shed solid pile cap disperses the burden of the structure into the pyramids. A parallel structure to a pile cap is a construction, which is a solid base floor laying without deviation onto yielding ground which may be accountable to falling in.

• As per Indian Standard 2911 (Part I/ Sec 3) -2010, the pile cap can be created by supposing.
• that the burden from column is distributed at 45° from the peak of the cap up to the central.
• Deepness of the pile cap from the foundation of the column or pedestal. The result from.
• piles can as well be used to be dispersed at 45° from the margin of the pile, up to the
• Central deepness of the pile cap. On account of the utmost bending moment and shear
• Forces must be effective at important sections.

Postulations Included:

• Pile cap is absolutely stiff.
• Pile heads are joined to the pile cap and therefore no bending moment is
• Passed on to piles from pile caps.
• Considering the piles are undersized and expandable columns, the dislocations and stress dispensation are planer.

Blueprint Considerations:

• Form of pile cap.
• Deepness of pile cap.
• Quantity of steel to be offered.
• Preparation of reinforcement.

Blueprint Modus Operandi:

• Decide quantity of pile.
• Pile cap preparation and plane measurements.
• Pile cap introductory deepness.
• Verify forces in piles.
• Confirm for thumping shear.
• Test for shear.
• Blueprint of moment.
• Test for connection.
• Information about reinforcement.
