A Review on Interaction Effect of Pile under Vertical Compression

Abstract

The present theories and methods for design of the vertically loaded pile foundations generally provides the overall values of bearing capacity and settlement characteristics for the pile groups. In every design criteria for vertically loaded pile system, there are some factors affecting on major scale such as bearing capacity, Settlement, skin friction etc. This review paper shows that the consequences of vertical load on pile foundation done by various researchers and from their results help in predicting the load–settlement behavior of vertically loaded pile and pile groups. It is observed, when the group efficiency is close to unity, the variation between expected and observed behavior of piles proves to be a positive approach towards the ultimate load. Hence, various researchers have tested and published their laboratory and theoretical values on load-settlement characteristics under the influence of vertical load on pile foundation. This paper illustrates about comparison of various test results and their research gap on consequences of vertically loaded pile foundation.
