Numerical Modelling of Axially Loaded Helical Piles: Compressive Resistance

Helical piles are foundation systems used to support compression, tension, and lateral loads. However, this type of piles was used around the world for more than 25 years. Its behavior, especially in Iraq, is still unknown and scare. The present study is carried out by analyses of this type of pile...
