Common boredpile sizes range from 30 inches to 60 inches (750 mm to 1,500mm) in increments of 4 inches (100mm). This article compares the structural capacity calculation of bored piles in compression using three design codes: ACI318, Building Code Requirements for Structural Concrete and Commentary; the Eurocode (EC2); and CP4:2003 (Singapore ...

· Single pile design in accordance with ACI 318 (2014) Piles are long and slender members which transfer the loads from the superstructure to deeper soil or onto a rock with adequate bearing capacity. Materials used for piles may include wood, steel, and concrete. Installation of the pile into the ground may be driven, drilled, or jacked which ...

Elevated pile caps of concrete pile component are taken as an example to analyze the process of damage, and the change rules of displacement, deformation, and damage of concrete pile are obtained. Marine corrosion and freezethaw environment will bring serious damage to marine concrete structures, leading to affect the safety and service life of structures.

· Castinplace concrete piles, or driven shafts are two great examples of how the can be produced (made) and installed. When choosing a pile type, one should generally consider the following conditions: 1 Poor quality of upper soil layers. 2 – When we have expansive soil in construction site. 3 To resist uplift forces.

Pile foundations are used when the underlying soils are incapable of resisting the loads from the structure. The piling is placed in the ground through poor quality materials to bear on competent soils. The piles are either driven into the ground or holes and filled with reinforced concrete. The piles transfer the load by bearing on competent

Concrete Piles Concrete piles in New York are precast and prestressed. The piles are cast in a precasting plant and then transported to the site. This creates a pile made of high quality concrete under controlled casting and curing conditions. The process is overseen by an inspector assigned to that plant.
