ABSTRACT
While helical piles and screw anchors have been around for decades and used in a variety of industries, they haven’t been widely used to support substation structures. By employing an innovative structural grillage with integrated multi-pile foundation design, which allows for adjustment in multiple directions for ease of installation, the grillage can be designed to transfer the forces from the substation structure to the helical piles. This paper will demonstrate how using some basic principles of structural engineering coupled with finite element analysis, an innovative structural grillage was developed to transfer typical substation structure forces into the helical foundations. The designs were confirmed by full scale testing. This paper will provide detailed and informative design information and test results.
