APPROPRIATE DIAMETER OF PILE FOUNDATIONS AFFECTED BY KINEMATIC AND INERTIAL INTERACTIONS

Abstract

It is known that the bending strain of pile foundations is generated not only by the inertial interaction due to superstructure, but also by the kinematic interaction due to large deformation of soft soil layers. Therefore, it is highly necessary to investigate the characteristic of pile bending due to kinematic and inertial interactions. The present study focuses on the appropriate diameter that minimizes the bending strain at the top of the piles when subjected to these interactions simultaneously. In this research, the relation between the diameter of pile and its bending strain is evaluated based on theoretical approaches. As a result, the appearance of the adequate diameter that minimizes the pile bending strain and its conditions are found and their characteristics are investigated.
