Abstract
Practically there is a wide range of pile types available for applications with respect to various soil types and structural requirements. When a pile foundation is decided upon, it is necessary to determine the required pile cross-section and length based on the load from the superstructure. The allowable stress in the pile material is usually a code value and the soil properties were identified from the initial soil investigation program. It is necessary to determine if the piles are adequately designed and placed. Pile capacity determinations are very difficult and complicated. A large number of different equations are used, and seldom will any two give the same computed capacity. There are many available equations to estimate pile capacity with respect to geotechnical approach done by Terzaghi, Peck, Parry, Meyerhof, Bowles and etc., but equally important is to establish an equation to estimate the structural capacity of the pile material. In this view, this study will be concerned with the presentation of equations to estimate the structural pilecapacity. Structural capacity of pile will be determined using the method used in designing a concrete column under ACI Code. Since the pile is supported by the surrounding soil, column slenderness effects may not be considered to make the design considerably simplified.
Keywords
