Evaluation Conduct of Deep Foundations Using 3D Finite Element approach

Abstract

In most practical situations, the pile either include circular or rectangular cross-section. The pile with circular cross-sectional shape usually analyzed in previous studies and little for the second type. While, no studies included comparison between those common types to understand and recommend which is batter for case of deep foundations. Therefore, this study is mainly deal with the vertical pile response under vertical load (i.e. no horizontal loads) when take into account the shape factor. To achieve the objective of this research, 3D finite element approach has been used to simulate the whole deep foundation case study. This study includes many factors, such as pile depth that measured below ground surface, soil strength parameter and soil types. It can be seems that little influence of shape factor on the vertical performance of deep foundation. Therefore, it can be recommended that if no any source of lateral load, it can be used any type and it is depending only on cost of pile types.
