Concrete Pile Foundation Calculator. Some of the standard design checks that are performed for the design of piles foundation: Geotechnical capacity check is completed when the end-bearing capacity of the soil is determined by dividing the applied vertical loads by the load-carrying capacity of the soil. The ratio should not exceed a value of 1.0.

Figure 3: Foundations options for tall buildings Raft Foundation. A raft foundation, also known as a "mat foundation", is essentially a continuous slab lying directly on top of the soil that extends over the entire footprint of the building, thereby transferring its weights and the loads to the ground in a more even distribution.
d. Piles with closed ends can be driven to avoid the ill-effects of groundwater. Disadvantages of Driven Cast In-Situ Piles: a. Driving of piles would affect the safety and stability of the nearby structures and service lines. b. Concrete cannot be inspected during or after the construction of the pile. Method # 3. Screw Pile:
The Friction pile transfers the load from the structure to the soil by the frictional force between the surface of the pile and the soil surrounding the pile such as stiff clay, sandy soil, etc. Friction can be developed for the …
In Adequate Strenght of the Concrete; Generally, piles are cast from the grade 30 concretes. This value may vary from country to country. Inadequate compressive strength of the concrete in the pile leads to severe issues in the construction. Since the pile is an underground structure, it is very difficult to rectify.
An architect of the same period, Félix Candela (1910-97) took concrete in quite a different direction. Born in Spain, Candela emigrated to Mexico when he was 26. He reshaped the capabilities of reinforced concrete into thin shells that could carry the curvature of concrete out into space.
This report presents recommendations to assist the design architect/engineer, manufacturer, construction engineer, and contractor in the design, manufacture, and …
The slump for concrete for pile foundation should be as follows: Sl. No. Types of pile: Minimum Slump: Maximum Slump: 1: Driven cast-in-situ piles: 100: 180: 2: Cast-in-situ bored piles : a) Water free unlined bore with wide space reinforcement: 100: 180 : b) Tremie concreting: 150: 180: 3:
Pile foundations supporting large structures (such as high-rise buildings, oil drilling platforms, bridges etc). are often subjected to eccentric lateral load (in addition to the vertical loads) due to the action of wind, waves, high speed traffic, and ship impacts etc. The eccentric lateral load, which is usually cyclic (repetitive) in nature, induces torsion in …

The concrete is compacted, and some is forced out of the bottom of the casing, forming an enlarged bulb which increases the pile bearing capacity. Aggregate piles. Aggregate piles, or stone columns, mean that compacted aggregate is used to form the pile, rather than concrete. This type of pile foundations works using the following …
